Definitely yes on the horses. If your interested, another great set is the $20 Prairie Meadows (Altoona, Iowa) set of 5 Racing Greats:

Seabiscuit, Seattle Slew, Secretariat, Sir Barton & Whirlaway.

These are not seen too often on E-Bay, but pop up from time to time. Expect to pay $35-$45 each for these (just a guess on the prices).
