Here is an example of the business address marker. This form of storefront sign was common in the garment district and other areas of New York City- where the simple "sign above your store" was impossible given the immensity of these buildings and the large population and diversity of businesses within. Along the length of some buildings, you will see the traces of these address markers on every floor.

It was not uncommon to see companies advertising constituent products for a final larger product as you see in signs for "coat fronts" and here for raw furs. It is interesting to see ginseng sold next to animal furs.
