German Greeting Card

I found this greeting card in a box of letters and papers by the side of the road. The ephemera and letters ranged from late 1800's to mid 1950s. Many of the letters were to a soldier in WWII. He had a German last name and a few papers were from friends in Germany. The card front has an inlaid print of Schwind's Honey Moon painting. Inside, was another loose print on card stock (as seen in the third photo). I can't decipher the artist name. The card is signed by quite a few people. A close up of the printer's mark is the last photo. Can anyone tell me the maker's name, the inserted print's artist, the possible date of greeting card?
