Question about an antique

Hello, I am fascinated by all this history. A really neat forum. I have an antique ashtray that says on the side of it "NORDDEUTSCHER LLOYD BREMEN" It looks to be pretty old. It is white porceilan with blue lettering and it looks like it was a cigar ashtray judging by the size of the slots on the sides. My question is, would this be of interest to anyone, and is it a particularly rare item or just a cool conversation piece. Thanks.
