Very rare Series 4 Headmaster, Skullcruncher.   This well-presenting MISB example includes crystal clear window and clear bubble showcasing the toy within.  Each end is factory tape sealed with no colorbreak whatsoever along the edges.  It appears the baggie within the box has attached to the tape that seals one end, and is visible at the outer tape seal.  The reverse exhibits a flap crease commonly seen in the Headmaster release.  Vintage Child’s World/Children’s Palace price tag stickers adorn the upper corner.  An elusive piece that hardcore Transformers collectors have been waiting patiently for. Encapsulated by AFA (80, 80-85-85), #12920979
