I have a couple of sets I put away in 75-76 They came in a white box with a brown green packing tape sealing the box. I can spot one of theses sets at a show from two aisles away
. Always liked this set as I felt someone needed to stand up to Topps because the quality of their cards was falling rapidly through the 70's. Topps bullied SSPC in court, but from the court rulings came the "gumless" baseball card sets from Donruss and Fleer in 1981.
I had a autograph experience similar to the previous post I was trying to get a 1975 SSPC Yankee set autographed and got a couple at my local mall Catfish etc. but at a card show( I think in 76 or 77) a player said he would not sign SSPC cards so I put the project down.
I may go out on ebay and buy one of the so called second printing sets and put together a list of variations. Anybody else interested? let me know we can compare notes.
