[Original artwork for a notice for an illustrated lecture by Walter Käch]

It’s September 1966 and Walter Käch, “a teacher at our school,” will be giving an illustrated lecture about pictorial symbols in early Christian times. One of the great Swiss letterers and letter-thinkers, Käch could not trust the promotion of his talk to just anyone. He wrote out this promotional flier himself—and this appears to be an original, directly from his pen. The talk start at 2:30 at the lecture hall of the Museum of Applied Arts in Zurch. See you there.
