Hi bookbndrbob

I believe the stamp shows , in fact, a Lorgnette.

From Wiki:

A lorgnette is a pair of spectacles with a handle, used to hold them in place, rather than fitting over the ears or nose. The word lorgnette is derived from the French lorgner, to take a sidelong look at, and Middle French, from lorgne, squinting. Their precise origin is debated: some sources describe English scientist George Adams the elder as their inventor, while others cite his son George Adams the younger.

"The lorgnette was usually used as a piece of jewelry, rather than to enhance vision".

Fashionable ladies usually preferred them to spectacles. These were very popular at masquerade parties and used often at the opera. They were worn popularly in the 19th century. The lorgnette was employed as a prop and affectation by early 20th century trial lawyer Earl Rogers, and one is featured on the front cover dust jacket of his biography, Final Verdict, by his daughter Adela Rogers St. Johns.

O.k., I stand corrected.
