A quick Question... what constitutes whether something hybrid is a Souvenir Card or not...? Take a look below:
If I were to follow SCCS, it would be NOT be a SC but rather a PV311 Vignette Engraving:
BEP Portrait/Vignette Cards
The Bureau of Engraving & Printing has printed examples of their work on cards going back to the 1870s. These were often bound into specimen books and presented to dignitaries, but some individual prints of portraits and vignettes were also sold. In the 1960s, the BEP started reprinting portraits of chief justices and presidents, and vignettes of historical buildings, mostly in DC. Some of these remain on sale today; they are fairly inexpensive.
These cards usually have only the portrait name or vignette title and don't commemorate an event, so they are not considered souvenir cards. But they have been given catalog numbers in the SCCS numbering system. There are more than 85 different engravings.
Things get interesting here as it has a FPS-1939A, which is a SC, right?
Thanks for any help, I have a few of these going up for sale and want to list it accordingly.
