Mini Advertising Cup, Al-Car/Ford ARS Bohemia

THis is an unusually marked mini mug. On the front it has a logo and Al-Car. On the other side is the Ford Logo. On the bottom it is marked ARS Bohemia, Brass. Ind. and Szakmary. I don't have a clue to where it is from or where I even picked it up, but maybe someone will know it!
