My guess is that they are sample boards !! They are machine made !! Not hand carved !! Could be anywhere from 1880 to 1920 or so !!

Thank you! Makes sense. The backs are just flat. I thought they were pretty to display but, also interested in figuring something about them out.

How does the back side look ?? Just flat ?? These were probably used to create the molds,,they are not molds themselves !! Could also be sample pieces just to show potential customer what each looked like !!
