The Flapper Era House Dress - a rare bird indeed

I was so excited when this late 1920s/early 1930s beauty unexpectedly came into our collection.  These house dresses (or, more technically, Hoover Aprons) are extremely rare - most were worn into rags.  Many, such as this one, came with a stamped design ready to be embroidered.  

 If you look closely, you can see the faint blue line of the embroidery guide.

The last two images are from the Fall & Winter 1920/1930 M.W. Savage Company
