1930s vintage friendship quilt w/ embroidered patchwork sampler quilt blocks

We love this old patchwork quilt... it was made as a friendship quilt, and the quilt blocks are all different, each handmade and signed with embroidered letters. Overall size is about 68" x 82".

The blocks vary a little in quality and condition (some were pieced of scraps, other from 'rag bag' fabric), but the piece as a whole is charming.

This came out of the estate of a lady who was a UW student at Madison during the early 1930s, but aside from that we know nothing more of it's possible history.

There's noticeable fading to the cotton backing fabric, and a little yellowing and soil from many years of storage. We saw a few short seams which have come unsewn, but this doesn't really look as though it's had much, if any use.
