morning glories 5.5x7

I'm not sure what kind of flowers these are. Some students found them in the school garden near the pumpkins. I think they might be some sort of squash blossom. If anyone has any ideas please let me know. in the mean time, I'll ask someone at school who knows. I'm starting this one off at $1.00 on eBay. The consensus is in (plus I heard from someone who knows these particular plants in real life). They're morning glories. Thanks for the help everyone!
