This is a very unusual, stamped cloth pattern, for An Improved Chemise Yoke. It was copyrighted or patented in 1868 and boasts a stamp from The New England Stamping Company. The pattern is a sweet, simple scalloped floral and eyelet design. 

It measures about 22" x 14" and is in very good condition. Someone started to work the sleeve section in the lower right-hand corner. 

There are a couple or 3 small light storage spots. This was never washed. 

Never seen one!
