My grandfather was an Optician in BelAir, Maryland. (He passed away around 1948 at a very young age). This boy with spectacles was placed next to another young boy, a tall piece wearing very dapper clothes and spectacles as well, in the front window of his storefront.
This piece is a Heubach painted porcelain bisque . The young boy is smoking a cigar or stogy. He has wonderful eyes that seem to follow one around the room!
He is in excellent condition (note detail on his collar) but it is possible the color of his hat is a tiny bit faded but I am not sure.
I found this info concerning the mark...
"Occasionally in the world of antiques, you may come across a mark, DEP, which could mean either Depose or Deponiert. This mark is commonly found on German or French bisque dolls, celluloid, porcelain, jewelry, glass or metal goods. Dep stands for the German word Deponiert which means registered, or copyright. some of the most common words that are found or may be found on French or German antiques and vintage collectibles."
