Any Info On These??

I as reading another related thread and it peaked my curiosity so can anyone provide any further info on this guy/business? Or tell me how to do research on my own? I'm just now realizing the potential awesomeness of the old covers! This site has opened up so many new doors for me and I'm thrilled! Thank you so very much! What Scott# is that stamp also?

This is a slogan flag cancel from Philadelphia Station S. Amaerican Postal Supply Co. Model B38. This machine 2 was in use from 1899-1913.

You rock Russ! Thank you.

Just for fun looked up the 1900 census -- shows Henry H. Cope, age 50, with wife and children, etc.
That was easy because Sellersville was small. Checking J.H. would take more work.

If you would like to investigate further the names and addresses on cards or envelopes I suggest using familysearch.org or ancestry.com
familysearch is run by the LDS church and is free. They have a huge microfilm database which can be used on loan. Ancestry.com is run for profit, though it gives good leads for free. You can follow up by subscribing or using a library edition. There are many many more sites of use, etc., but these two I have found are good starting points.

wow thank you for the cool information!

You could also google the company name or check out wikipedia for a reference point.
