Wow, some amazing beer mats from the 60’s in this flickr set.
“These were all donated to the Save the Children shop where I work on Saturday mornings. They all date from the early 60s – a few have precise dates in pencil on the back from 1962 or ’63. Most have the same graphics on the back as well as the front. Where they differ, I’ve scanned both sides.”
