Photo ID Help
 

Anyone have any ideas on these? Possible years or team would be nice. I dare not hope for actual player ID's. I'm thinking the vehicles visible in the shots could be the biggest clue, but I'm clueless when it comes to dating them. The original photos are tiny (about 1-3/4" x 2-1/2"), but I can blow up any details as needed.

Really, I'm not expecting much in the way of breakthroughs, but thought I'd throw them out there just to be sure.
