Tobacco tin?

I can't remember where I got this.I've been tryin to identify it for a while.It is 3" across and 1" deep.It has a vine design on top and an image of a bat with a fruit tree or bush.I believe it is copper plated tin.Any ideas as to what this is?I'm thinking it is a tobacco tin or snuff box. I've looked at picture 1 and the bottom portion it shows a bat but above the bat is what I now believe are opium flower pods. Any comments on this observation are appreciated! Christo
