Thats what i think as well, which is cool because of where it was found.The image on the one being held looks like a dam and lake.
Im no pottery expert by any means, but I believe its old. Not super old, maybe 1800's, maybe newer than that. One thing is for sure its older than 1950, due to where it was found.I believe it’s glazed so if a more modern time. I’m sure others will weigh in.
