Offered here is a rare and long-retired item, a 2007 Curious George Hopper Ball by Kellytoy. This is the less common blue, "Ride 'Em Cowboy" version, as indicated on the box. I have read online that these were promotional items for the show, which aired on PBS.

Condition:

Inflatable is new and sealed in original factory bag. Outer carton is not sealed, although it may not have been sealed at the time of its release, I'm not sure. Carton has some wear (see pictures), but is generally in good shape. 

Thanks for looking!
