Even though this plate does not state it, I am sure it is a souvenir of Niagara Falls. It is the early milk glass that has the opalescent edges that can be seen in picture #4. The border has feathers & cartouches that are painted gold. There is an inner beaded edge. The falls are painted white with green foilage, brown rocks, and gold berries. This plates has a 7-3/8" diameter and is 1" tall. This plate has no markings.
This plate has been handled through the years. There is some wear to the paint. One tip has a slight chip that can be seen in picture #5. It was not an easy picture to get - but you can see that the edge has a dip in it.
