Imagine Fungi hand painted decor

this imagine sign was a thrifted piece of decor that I hand painted. It is very heavy but I’m unsure of what material it is. I primed and painted and sealed it so I know the art will last if kept indoors. it features different fungi on each letter and dots in the edges. Measure approx 13.5” across, 4” high and 1” thick Meant to be used as a piece of decor on your mantle, bookcase, altar, etc. it does not have a hanging mechanism though I think a nail under the M and the E could hold it up.
