Card Identification Forum

I can't find anything on these cards. I believe it is a series because there are several other cards advertising for J & P Coats thread on ebay. They also have two dogs on front with the artwork by Schummacher & Ettlinger. 

I'm hoping there is a checklist out there somewhere. The American Card Catalog does not do a thorough job of covering some catagories.

I know this is kind of an oddball, but any help would be appreciated.
