Vintage Ultima / Ultima-inspired Brass Ashtray #1

This is one of my favorite pieces to collect, you don't have to smoke to appreciate the craftsmanship and design that went into pieces like this solid brass ashtray. It's hard to say whether this is a real Ultima or if it was inspired. Bäckström & Ljungberg created the Ultima ashtrays but sent out the work to many different foundries around the world, from what I can tell. So this and the other that I have, despite being slightly different from one another, could both very well be authentic. 

Authentic or not, these are authentic antiques, surely from at least the 70's. Heavy solid brass with wonderful patina!
