These are the 3 Postal Stationery envelopes in my collection.
If any one can tell me any thing about the senders it would be much appreciated.

2. Cohen Bros & Co, New York 16 Dec 1905



3. New York Philatelic Exhibition

Thanks

Did you try Google? A search "R. P. Elmore Company" will tell you what you want to know about the first cover.

For the second, I had to resort to my newspaper.com account to find anything, and even then I found only one relevant hit, but you can get the idea of what kind of business they were in from it (sorry about the slight blurriness to the image, but it is readable):



Question doesn't seem to apply to the third cover.

blcjr,
Excellent informative post!

Dry goods is very much what that part of Broadway was all about in those days.

blcjr,

Thanks for the very informative response.
