Accordion Patent T-Shirt

A perfect design for any accordion fan who's also perhaps technically minded and always wondered what the inside of a box looks like.

The design on the front of this shirt is one of the original patent diagrams for the accordion which was submitted. It's a piano accordion keyboard on it, and all the parts are labelled, the bellows, buttons, keys etc and some of the inner reeds and valves too.

It's an unusual design, perfect for any box players out there.
