I was at the card show last month. I had picked up my Earl Wilson cards and was wandering around, looking at the cool things that vendors had (many 1960's entertainment cards, tons of toys and games) and looking at my watch, knowing that I had to beat it home for my wife's cousin's wedding.
One dealer had boxes and boxes of sports magazines, game programs and photos. A buck each. I didn't find any magazines that I had to have, but I did find this unpunched set of McDonald's football cards.
I don't remember these cards being issued. Individual cards measure 2-1/2" x about 4-3/4". They were produced by Fleer. Looking around on the ebay it appears that there were also sets (3 sheets of 6 cards) for all 28 teams and an All-Stars set. I've got the All-Stars.
Not bad for a dollar.
