A stamp?

Been playing around with ideas for a logo and a stamp (we want a stamp! we want to stamp things!)

 

There's a great rubber stamp maker in the East Village (Casey Rubber Stamps) who we're going to take our design to.

Any suggestions?  I know we can't legally bottle and sell yet, but drawing a cup wasn't very fun. And we do hope to one day be able to bottle our stuff to distribute at least within New York.
