After seeing this window, I realized I have a good excuse to visit Amsterdam.
Typique printing studio, run by René Treumann, was established in 1967 in Amsterdam. Alongside to the main activities; stationery, business/wedding cards and birth announcements, he prints limited editions typographical cards, posters and monoprints. The works composed from letterpress material are my favorites.
