Caesar Miniatures makes three sets of sports figures, I got the basketball players. The astronauts include a space capsule. The War Against Fascism set is awesome.
I ran out of table leg material and got more at Pegasus. The troops came from there too.
These Caesar sets are very good.
MRS Bunkermeister found these at Michaels. You put stuff on them that you want to paint so you can paint all the way to the bottom without painting your tabletop.
Each set has baseball, basketball or soccer. I got basketball.
