I think I have seen this design in a book someplace, but regardless of where it came from, this person did a great job carving. It's a wonderful pumpkin and I wish I had the talent to carve one like it. Kudos.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
