PAINT, GLASS, AND WALLPAPER STORES (SIC 523)

Establishments primarily engaged in selling paint, glass, and
wallpaper, or any combination of these lines, to the general
public.  While these establishments may also sell to contractors,
they are known as retail in the trade, even if sales to contractors
account for a higher proportion of the sales. Establishments which
do not sell to the general public are classified in wholesale
trade.
