If you want the poster and are in Germany, hit me up, I’ll print it for cost of ink on good 8 colors printer and hahnemühle paper.
For anyone still interested: I can print a bit larger than A2 format: 43x65cm, the cost is around 4 euro for a print on glossy 190g/m2 epson photo paper or 11,1 euro for Hahnemühle Photo Rag 308g/m2 matte paper (that one is expensive but really good).
Edit: yes, I'd be happy to print the poster for you, feel free to write me!
Anyway, thanks for all your kind words and little stories!
P.S. this is how it looks printed on Hahnemühle Daguerre Canvas (colors are a bit more saturated irl): https://rybakov.com/files/unix1.jpg https://rybakov.com/files/unix2.jpg https://rybakov.com/files/unix3.jpg
