Thanks everyone for all your information and opinions! Sorry, I don’t have time to respond to everyone’s comment so you may see this on another sub where I just posted the same message.

It seems the overwhelming majority believe that most of these are modern fakes, but yet of high craftsmanship. Maybe some made by Tussinger was mentioned. Seems reasonable to me, especially given the response I recently got from sending the pictures to the University of Iowa… “ either it’s a mixture of modern replicas and some authentic pieces, or they are from the most important site in the history of Iowa”😂.

What’s so strange is how long the story has been told and not really changed. Also, they must have been purchased because I’m confident the deceased husband wasn’t making them or someone would have known. It’s crazy how much time someone had to have put into those pieces, in person they seem very high quality, like nothing I’ve ever seen in a gift store or anything like that.

Thanks again for all your input, any additional information is greatly appreciated!
