Are Postcards Printed With "Guaranteed Real Photograph" Always RPPCs?

Hello. I'm still fairly new to postcard collecting and I'm trying to nail down terminology in terms of postcard types. I recently acquired a good size lot of postcards and some of them have "Guaranteed Real Photograph" printed on the back. The images are glossy, but don't have the telltale "silvery" look that many old RPPCs have. Perhaps this is because they're not quite as old? Here's an example:







I'm just trying to make sure I don't classify anything as an RPPC when it isn't. :) Thanks ahead of time for the help!

"Real photographic postcard" properly refers to an image directly printed on postcard stock from the negative, usually by a small, local photographer. Postcards such as yours are mass-produced printings by companies, not directly printed from a negative.

Thanks for the reply. I knew it was produced using a real photograph but, unless I've missed the mark completely, whether something is an RPPC or not has to do with the printing method used. Meaning, a halftone or lithograph postcard may be based on a real photo, but are not printed like a real photo… so do not qualify as RPPCs. My question is whether or not this (and postcards like it) that say "guaranteed real photograph" would qualify as RPPCs, as I'm not certain what printing method was used.

This is what I figured, but I wanted to be certain. Thank you.

This may be a silly question... but do you know what "type" of postcard this would be considered?
