Karel Martens：情書

The way each envelope is individually printed with such care makes them feel more like little artworks than simple mailers. I’ve already framed a few of my favorites from the set.

The stamps and postmarks on these envelopes are the real draw, but the hand-printed textures on each one make just flipping through the 46 pieces feel like a quiet little archive. It’s a very specific collector’s item, though, so unless you’re into graphic design history, it might sit on your shelf

I bought this for the envelopes themselves, not the letters, and the printing on each one is genuinely intricate. Forty-six of them, all handcrafted, and I keep flipping back through to spot small details I missed the first time.
