Atterbury milk glass swimming retriever platter

Took a look through the milk glass section and didn't see one of these milk glass Atterbury swimming retriever platters. I've had this one for about 25 years, but don't remember where I got it. I have it sitting high on top of a cabinet to protect it from my cats and forgot to measure it before I put it back up there. Not going to attempt to get it down again. I think it is something like 13" l x 10" w. I don't see these much any more. Maybe no longer desirable? Too old fashioned? I think they were made pre-1900.
