What are these huge Skeletons and Skulls?

They're entries in a photoshop competition from yonks ago.

1 and 3 are obvious fakes.
2 is harder to figure out

Hya..Greece...Photoshop?...Do you have link to the Orginal source???...These days "you cannot just trust images...Thank you foe posting...Indy

When I went to England I went on a tour of castles and there were some knights armor in one site and I asked if they were for a child and was told they were for an adult, people back then were not very tall, little over 5 foot so any one 6 foot or better would be thought to have been a giant, Guess that's why women wanted to mate with the north men aka vikings.

Good luck op!

These threads don't go very far.

I would stop questioning these pics ;)
