I walked into a junk shop on Monday when I got back from Vegas and this was the first thing I saw. It's a Homer Laughlin Plate, I'm guessing that it is a souvenir plate (it's not a full size dinner plate but almost 7 1/2 inches in size) but Homer Laughlin made mostly china for hotels in the 50's and 60's.
The plate can't be any older than 1956 since the Hacienda is printed on the plate (upper right hand corner).
I'm sure it's not worth more than a few dollars but it's a nice addition to my collection.
