Universal Imperial Inflatable Frakenstein.

[ozfx]

  Hi everyone.
Today I attended a Halloween garage sale.  My son bought a 6 ft inflatable Frankenstein for $10. It was brand new. The box had some wear. But the Frankenstein was never inflated. It's the Imperial 1987 model. Now he's thinking of putting it up for auction on ebay. He thinks it may be worth more than he purchased it for. I think so too. Does anyone know just how much these inflatables go for $$.
Any information would be much appreciated.
Thanks.
