You all know the bobble head dolls, created from resin plastic in the likeness of popular sport players, political players, television stars, singers, etc... I didn't know this, but these are believed to date back to 1842. Around 1950 the first modern bobble heads started to appear in the United States. The process was a bit limited though. The dolls all came out with the same faces and body style. It kicked up a bit in 1960 with them being produced for some of the players in the World Series. They were the first player-specific baseball bobble heads.
As you can see, non-traditional shapes can be done. I think they would be a big hit. Again, here I go with the value of giving away the unexpected. Check out the traditional shape with a not so traditional look.
