i bought four mini snifters from the brewery over christmas time when picking up my bottles. they are more closed off at the top as a true snifter. your pic looks like it may be more straight like a dogfish head glass... mine had the same images though.
from this angle these kind of look different from the OP's... or at least i thought they did... but from this angle i'm thinking they are the same now... oops.
it appears as whoever can get these would be quite popular and have a good amount of beer/glassware coming their way.
