Interesting Old Postcard

Why, you ask, is the egregious example of tweeness interesting?
Okay, first, it’s dated.  1911, on the back.
It’s addressed to Blanche Gladson in Rogersville and I see a lot of cards addressed to her.  It’s from her brother, Hal.
It’s pre-WWI, embossed, and probably lithographed in Germany.  It was never mailed.
It’s got “postcard” printed in 13 different languages (it’s “open mail” in Russian) on the back.  There’s also either a printer’s mark or a guild mark in the lower left on the back.  Ask me if I care…
So, in Japanese, it’s “kawaii!”
