OK. As promised. Here are a few of the cancels I have been talking about.
1st: A "paid all C, without date" cancel on a Germany #8 postal card, year 1878

2nd: a "paid all C, with date" cancel on German postakl card # 14, 1886

3rd: Here is a "paid all PO" and a F-NY cancel" on German Postal card # 14, 1886

4th: A Philadelphia version on Germany #25 postal card 1890

5th: A Boston Paid version on England postal card #21, 1892

And finally 6th: A "PONY" receiving mark on a England # 21 postal card
There are a bunch of these types of cancel on incoming foreign mail in the US. New your has quite a few varieties.
Again, anyone know of a catalog listing of these cancels?
