From what we can only imagine was the gift shop of the Thomsonite Inn on Lake Superior or something similar these small, polished Thomsonite "eye" specimens are in their original vintage retail packaging dated 1964. If anyone knows more please let us know! Card is 3" x 5". Grand Marais, Minnesota, USA. Most are in pretty good condition for their age, Some have more smaller, some have fewer, larger, pieces. Luck of the draw.
