This item is an actual entry card to Stan Musial's restaurant in the 1970's. The restaurant was named 'Stan Musial and Biggies' and was located on Oakland avenue across from the St. Louis Zoo and just down the street from the old Arena (where the St. Louis Blues played). None of those buildings are standing today unfortunately.
This item is made of plastic and quite durable. The seller had this personally autographed with a Stan The Man COA Letter.
