He Sells Sea Shells

This is a interesting hand-made (I assume?) piece, wooden frame, felt background and a mélange of various shells. There's one tiny remnant of glue, just center left to the top of the primary shell where you can see a small piece has fallen off, which isn't too bad considering similar items I could source online date back to the 1940s, making this one of the oldest mixed media pieces in the shop.

As I prepared this piece for photography, I tried to recite the classic tongue twister and I realized, I really only know the first line of it. Do you remember the rest?

Apparently, it goes..

She sells sea shells by the sea shore.
The shells she sells are surely seashells.
So if she sells shells on the seashore,
I'm sure she sells seashore shells.

Which is absolutely news to me as I'm selling these sea shells from the 4th floor of an apartment building.
