The hand holds would have been hard to edit. It could have been a banner
they were holding, edited by modern photoshop techniques but even then,
it's very well done.
They didn't have the ability for special effects back then. They didn't
even have plastics. The creature is beyond a taxidermist skill which
would have been the go to person for this sort of thing back then.
It could be a modern hoax, but there are claims the photo's go back to
the 1960's which is decades before even home computing. They were still
using typewriters and TV was a new invention. So if these photos were
around in 60's, it adds to the mystery because they couldn't have edited
it in either.
