Rocking Beauty...authentic or knock-off  

Okay, before I chastise my hubby for shelling out $20 at a flea market for his "find", how do I determine if what he brought home is an authentice Creative Playthings Red Ball Rocker, or Rocking Beauty? He had no clue what he was buying, just thought it was "unique". After googling it I find that there was one reproduction in 2006 by DWR, or Knu. The one we have is stamped "creative playthings/princeton, nj" under the "seat". Minor wear on the red ball and edges of the rocker panel. It is a light wheat color and does not appear to be stained. In the few pics I have found, the only differences I see in one pic to the next is 1) the inclusion or exclusion of the stamp under the seat and 2) some have a horizontal peg below the top curved piece next to the stick that supports the red ball and some have it under the top curved piece. The attached link depics what ours looks like. Please and thank y'all in advance!
