Turtles all the way down
So now we have a world, a universe. The idea is, everything is happening in this universe all the time. But we can't know all of it. What we will do is slowly examine this universe, get to know its characters, learn the stories both in grand tidal waves and humble rippling eddies. Let's start here, with Maverick and Goose fishing.
The Olho de Boi: How Brazil's "Bull's Eye" Became the Americas' First Stamp
Some stamps earn their fame through rarity. Some through age. Some through error.
The Olho de Boi, which translates from Portuguese as the Bull's Eye, earns its place in history through something rarer still: it was the first postage stamp ever issued in the Americas, the first stamp ever printed in the Southern Hemisphere, and it arrived just three years after the Penny Black changed the world.
Hello PenPal Stacks, Goodbye Doomscrolling
Words are infinite. But infinity can be a bit extra. Infinity is doomscrolling. Infinity is the library of Babel.
"The Word God Is Nothing But Human Weakness": Einstein's “God Letter”, 1954
In January 1954, Albert Einstein was 74 years old. He had reshaped our understanding of space, time, light, and gravity. The world had named him a genius; presidents had written to him; he had been the face on magazine covers across five continents. And yet here he was, in Princeton, New Jersey, writing a private letter to a philosopher he had never met, a philosopher whose book he admitted he might never have read on his own.
That letter would become one of the most debated, most auctioned, and most read personal documents of the twentieth century. It is known today simply as the God Letter.
How We Designed a “Daily Freebie” Feature Without Inducing FOMO
Daily rewards are a dangerous game.
Done wrong, they quietly turn into obligation loops: log in or lose out. Miss a day, fall behind. Fall behind, disengage. We didn’t want that. Lettre is built around slowness, intention, and joy. We are no fans of anxiety disguised as engagement.
So when we set out to design our daily freebie system, we asked a simple question:
Can something be daily… without being demanding?
Here’s how we approached it.
The forgotten rituals of correspondence and how to bring the best of them back

Pippin’s Route: Charles Darwin’s Letter That Traveled an Empire
In the 1830s, letters did not move directly from sender to recipient. They relied on ports, packet ships, national post offices, and regional mail routes, often taking months to arrive. Each stop added time, risk, and human effort. This blog traces the realistic postal journey of one such letter Darwin wrote during the South American leg of the Beagle voyage, following its path back to England through the 19th-century postal system.

“The Great Light Will Shine”: Nikola Tesla’s 1900 Letter to the Red Cross
Long before radio astronomy, long before space probes, long before SETI, Nikola Tesla believed he had detected communication from another world and this was the idea he chose to share with the Red Cross (not a diss).
“Columbus Welcomed at Barcelona”: The Story Behind a Historic Stamp

“Are You Too Deeply Occupied to Say If My Verse Is Alive?” - Emily Dickinson’s 1862 Letter to T.W. Higginson
Emily Dickinson’s first letter to Higginson is a quiet reminder: Some of the most important human connections begin with uncertainty.
“A Love Letter That Outlived Its Writer”: The Story of the Blue Mauritius
Some pieces of paper carry entire centuries.
The Blue Mauritius, a small square of blue-green ink printed in 1847, is one of them.
Barely an inch wide, it has become one of the most famous postage stamps in the world and it’s not for its perfection, but for its imperfection: a single phrase that made it both a mistake and a miracle.
“Everything Here Strikes Me as Very Odd”: Louisa May Alcott’s Civil War Letter
The 30-year-old author, not yet famous for Little Women, volunteered at the Union Hotel Hospital in Washington, D.C., tending to soldiers wounded in the Civil War. Her experiences were grueling, tender, and transformative and she recorded them in a series of letters to friends at home. The letter below, written to Miss Hannah Stevenson on December 26, 1862, captures her humor and humanity in the middle of unimaginable fatigue.
The Z Grill: America’s Rarest Stamp and the Mystery of Its Tiny Diamonds
In 1868, the U.S. Post Office tried to stop people from reusing stamps by pressing tiny diamond-shaped ridges into them, a process called “grilling.” The rarest of these, the Z Grill, was applied to a few 1¢ Benjamin Franklin stamps. Only two survive today, one locked in the New York Public Library and another once traded for $3 million. What began as a postal experiment became a legend: proof that even the smallest marks in history can hold the deepest stories.
