I know they aren't the big stars, but her are 2 flyers from show my dad and his partner at the time promoted.
My father and I started setting up at shows in 1979. At that time Mantle and Dimaggio were $7. Williams was around there, but higher in Boston area. This quickly eslcalated through the 80's to $10 for pics and $25 for balls by 1985. By the early 1990's, Mantle, Dimaggio, and Williams were all over $100 per flat, with IIRC, Dimaggio being $175 for balls at a big Atlantic City show in 91-92.
