got a certificate of authenticity I keep inside of it, never been drank out of, not sure if you can with these, had a vader to but I sold it 4 years ago.
its from dramtree, they did a series of steins, vader yoda and this, artwork is by dave dorman, number 1395 of 3000 dated 1997 on the bottom, and its not for sale, but always happy to share pics with everyone.
I remember seeing these in the insider back when they first came out. I had forgotten they existed with as many new things have come out since then. Just reminds me of all the cool stuff I'll have to "catch up" on buying when i'm rich.
