No, actually the depression ended in 1941. I talked to the man personally in 1975 and saw the same “evidence.” He stated at that time that he needed money for an operation and the artifact was for sale. Maybe it is a different person, but I doubt it (maybe a relative.) The fact that he said he wanted to offer it to the Young Earthers kind of tells you where he is coming from. They have generated interest in this sort of evidence, so maybe he thinks he can make a “fast buck.” I don’t know personally—however, I have seen the footprints, and they are not human.
There probably is some good money to be made in creating dinosaur/human footprint “fossils”.
There’s not much market for selling Mazola as “snake oil” anymore, but this is a pretty good replacement.
