For my next number: "Lady of Spain."

Although of the accordion family, the box would be called a one-row melodeon these days. Unless those ladies are tiny it looks quite big for a one-row. It plays in one major key. Each button plays a different note on push and draw. The mushroom shaped objects should be stops that open and close different reed pads to alter the sound. There should be a thumb strap behind the button row, and the bass side, which can't be seen, probably has two buttons or levers, one for a bass note and one for a bass chord, again a different note/chord on push and draw.

"Another hour of this and I'm going to break that Accordion over her head"

... was later outlawed by the State of Maryland.

In Maryland? Probably more like: Niech dobre czasy!
