There is something fascinating and captivating about the original series toy artwork on merchandise, being so toy-accurate.
This puzzle that I found at Sandown Collector Fair on Sunday has artwork I've never seen before, but it is just so toy accurate, that you think your own toys could come to life.
Check out the double-jointed gun arm of Optimus though... one of the flaws of artists copying the toys exactly in the battle scenes.
(the puzzle only has 134 pieces, but it was only $5, and I would be having it on display as a box for the artwork, not as a completed puzzle)
