This is an advertising item made by Maker's Mark in the 60's or early 70's. Its a glass dish 8in x 4in. It has the Maker's Mark label slightly raised on the front and the back is smoked glass. The back appears black but If you hold it up to the light and look through it you can read the writing on the front, so I think its smoked glass. It was my father's and I know he had it in the early 70's. When sitting flat on the table its a little less that an inch high.
