I've only seen musical Nashco tole trays with a Happy Anniversary theme. This one is more generic, with a music box attached to the underside that plays Some Enchanted Evening.
The filigree rim tray is 15" diameter. It's hand painted with a big spray of roses and other flowers in shades of gold and cream on a white background. The painting is signed Francis. Three 1-3/4" brass legs are attached to the back, as is a hanging wire if you prefer to display the tray on the wall. There's a foil label reading Nashco Products New York Hand Painted. The music box plays just fine and the tray is in very good condition with nothing more than a couple of pinprick marks to the surface, though there is mild wear to the underside.
