My daughter's favorite games were with her Breyer horses.- both alone and with friends. She is now in her 50's (still a horse lover) and is finally willing to pass them along. There may be collectable value because of their age and type, but I didn't research that.
There are 9 beautiful horses with all their legs.
There are also 6 that we call wounded (missing feet or lower legs, the first part to break). With a support stick, like a piece of chopstick and tape, they could stand and be part of a "herd" as well as useful for other uses like art work.
All were loved.
$30 cash for all. You pick up. I can deliver locally (Costa Mesa or Newport).
