Marx or Marx Style Dinosaur Lot Allosaurus Hadrosaurus Pteranodon Plateosaurus

Found these at an Estate Sale. Could be Marx brand. See pics to decide for yourself.

The Allosaurus has some blue on it. See pics. I’ve not tried cleaning it so I don’t know if it comes off or not. The other ones could be cleaned up as well. See pics.

See pictures and zoom in for a more detailed description of condition.

For sizing the Hydrosaurus is approximately 2 3/4” tall.
