Pan-American Exposition Displays - Antique

Hello everyone - not sure if this is the right sub-forum but if not, please let me know where I should move this post. I recently acquired 3 wall hangings of the 1c, 2c and 4c 1901 Exposition stamps. They are older, I've been around antiques all my life and they definitely play the part of being from 1901. The size is 14"x11", I've included a beer can for size reference. The images are painted and seem spot on - this isn't someone's art project. I googled for a good period of time, and have not come across something similar. I figured I'd ask here as if there was a place someone would know what these are, this is it. Does anyone have any info on them? Maybe post offices received these when the issues were released? Any and all thoughts/info are appreciated. This is my favorite series of stamps to collect, once cleaned up they will be on my wall. Thanks everyone!

Private modern productions sold at stamp shows among other places.

Are there any markings on the back?

I posted about similar wall sculptures from the 1970s I acquired that, while they look like wood, are much lighter molded material:

There's no markings on the back - it's solid wood and old/cracked/warped at that. I cleaned one, the other two are next - they had alot of soot on the back and were exposed to a fire at one point. The ones that you posted are carved, these are just a layer of paint on what appears to be pine, if I were to guess -

Adding a couple pictures of the side of the 4c - they don't seem modern in that if they were from the 50s, I'd be highly surprised - the wire and nails for the hanging seem older. I can only attach photos less than 300kb so the detail is lost here, but in my hands these seem 100+ years old, I've had alot of objects of this age under examination. Maybe they are recent though, and had a rough life. The wood on two are warped, they are solid planks.

My guess is the 1970s, and they were stored or hung in a very high humidity environment like Florida that prematurely oxidized the hanging hardware and also resulted in black mold on the surface. Or someone left them in a garden shed in New England for decades. They're typical of wall art of that era.

I collect antiques and I only see this nail and wire hanging method used on things from the 40s or earlier. If you compare the style of these to the 1970s ones linked here, they are clearly a lot older. If it was newer, I would expect a nylon rope, thin chain, one of those tringle shaped hooks, or a hole. Also, if that is black mold, you might as well throw them out. It is very toxic to humans and will spread and destroy your other stuff. I have had to dispose of things I liked due to black mold.

Thanks for the heads up on the black mold - I was assuming that it was soot from being hung over or near a fireplace. I did test with a paper towel soaked in bleach, and the black powder/dirt on the back did transfer and make the towel black, so I'm hopeful I'm safe there. They are outside for now though until I can 100% confirm. Also the nails keep me thinking these are older - they are not perfectly round head, they seem like wrought head style. Possibly handmade.

those are totally cool!

I've confirmed it's just soot - they were in a room close to a fireplace for a long period of time per the previous owner. Mold tests were negative so that's good. I've looked all over Google for something similar to no avail. There was apparently a USPS booth at the 1901 Expo - this is AI generated but maybe it's true.

"A United States Post Office facility was located inside the U.S. Government Building at the 1901 Pan-American Exposition in Buffalo, New York. This post office branch sold the official "Commemorative Series 1901" stamps and applied special cancellations for visitors."

Not saying they are, but maybe there's a remote chance these were hanging in that booth? If they are indeed 100+ years old - as I mentioned, they certainly play the part well when in my hands, that's the only conclusion I have. If anyone has pics of something identical or other info, would be great to have them for reference. Thanks much everyone!

Adding 3 last pics as I've cleaned them up. The nail heads do appear from around the 1900s and earlier, they don't have the perfect roundness of later mass-produced nails. Also a closeup as the shadowing does appear to be hand-painted. If this is the wrong sub-forum for this post, I'll ask for it to be moved (and if you're an admin reading this and this is the case, please relocate :) ) These don't seem from the 1970s - and I haven't found any other examples so I doubt that the Post Offices had these hanging, there would be others out there. I have a couple hundred of these stamps in my collection, but I'm also an antiques fan with curiosity.
