Palitoy 20-Back Hammerhead with German Distribution Sticker: As you can see, this is a Palitoy Hammerhead figure. It's a 20-back, much like the one seen here.

The significance of the item lies in the sticker that's been placed in its upper right corner. It refers to General Mills (which owned Kenner at the time) and appears to indicate that it was distributed in Germany.
