Fiddlesticks I want to play with my toys

This is a very interesting toy that I recently found at a yard sale. It's called "Fiddlesticks" by Knickerbocker Toys. Not much is known about this particular toy that I could find. What really makes this toy interesting is the cross promotion of DC and Marvel in one product. This is a building toy where you have instructions to build what looks like the Bat Plane. The set comes with many different types of pieces, sort of in the style of Knex. What I really like is the 4 action figures that you get with the set. You get the Hulk, Spiderman, Superman and Batman. Now what child wouldn't like a toy where you get the best characters from both worlds without buying two different toys from 2 different toy companies.

Thanks and keep looking for those hard to find toys! www.vintageboardgames.net
