Picked these up tonight, but haven't found out really much of any info on them. They are photographs and they measure 3 1/2" x 5". Stamped on the back is the name of the studio "Newburg Studio" on 4th Street in Minneapolis. Photos are facsimile signed on the front. Players I have are Jim Pollard and George Mikan. A seller on ebay has a bunch of these that are autographed, but didn't offer much additional knowledge in the listing and has a Jim Pollard for sale. I have never seen another George Mikan.
Does anyone know what exactly these are? Approximate year? Value? Scarcity? Thanks in advance.
