What is this thing,, cant see it well !! Looks like a wall pocket ?? The patd, 10-31-22 indicates it is a commercially produced item,, not a sculpture !! Sculpture would have a copyright !! I think its cast iron and could be patinated !! The triangular mark looks like one I had on a cast iron doorstop from the 20`s !! It was Waverly Studios mark !!
They made many cast iron items for the home and many are quite collectable now !!

All you have to do is a web search for “list of 20th century bronze artists or sculptors” However many companies made reproduction bronzes with signatures !! Just different sizes from the originals !!
