These horns are generally defined by a stunning engraving of a "Mars takes over the earth" scene on the bells of these horns (I hope ya'll get the pun: Martian/Martin. Heh. Heh. Heh. Whatever).

These horns are occasionally called "Martin Skyline" horns because of the engraving.

Unfortunately, it's very hard to find lacquer horns in good condition, because the lacquer isn't really good (on any Martin), but the silver- and gold-plated examples are stunning.
