MIT has a glass blowing class for members of the MIT community. Throughout the year they work in teams of 6 or 7 to produce 1000-1200 pumpkins for the Great Glass Pumpkin Patch. The pumpkins are put on on sale with the proceeds going to benefit the MIT Glass Lab.
The pumpkin above was probably in the $400 range. The smallest pumpkins went for $25 with the larger ones going for $800 or more. Thankfully, they have a preview the day before the sale and it was free to take pictures!
