SHOP, THE NEW HARLEM WORLD SHOP!
The cast iron framed window advertisement is a attention catcher, with the little man in a white coat pointing at us reads:
Cigars & Soda
Coca Cola Drink
Toilet, Articles & Perfumes
If you look closely in the window the proprieter can be seen working in the store. Moxie was among the first mass-produced soft drinks, and today it is owned by Coca Cola. Via Source.
