Horex Ad

I found this interesting illustration in the May 1986 issue of the Classic Motor Cycle, it is apparently a vintage (no date given) ad for Horex motorcycles. The article goes on to describe the origins of the name, Ho from the town of Bad Homburg, where the factory was located somewhere on the map (possibly the lower right?) that makes up the background, Rex from the line of canning jars- behind the motorcycle- with which the manufacturer got its start.
The factory closed in 1959.
