The Cataldo family, who lived in Lorain (Ohio) in 1968, must have been somewhat perturbed by the sound of something landing on their roof. Was it a bird? Was it a plane? Superman, perhaps.
In a word, no. They then saw a huge face looking through their window. It looked like a lion. It ran off and they saw it disappearing into the distance. It left human-like handprints on the window.
I have a suspicion this may not have been a cryptid at all, but rather a man in a large mask. The outstanding question is, how did he land on the roof? I don't know, but I welcome suggestions.
