Embroidered Hearth Rug

New England, probably Connecticut, c. 1810-30.
A strikingly beautiful embroidered hearth rug in a most unusual and wonderful color palette, signed on the reverse by the maker "Mary Cole". While embroidered hearth rugs are themselves quite rare, this is the first one I have seen done on this vibrant indigo blue ground. 
Wool on wool.
63" x 33" mounted.
