In the original series the crew regularly drank coffee from grey cups. In one of the most famous incidents, Kirk discovers that tribbles have got into his dinner, eaten his chicken sandwich and drunk his coffee. The cups were originally made of styrofoam, whereas this is made of earthenware. We've also added a detail that you might have missed. When the cups first appeared in 'Where No Man Has Gone Before', they featured an Enterprise logo with a wreath, but it never appeared on them again. With a little help, we sourced that logo from Gene Roddenberry's files at UCLA and have included it on this cup. The tribble is removable, so your coffee should be safe. BRAND NEW IN BOX. This box has slight damage as shown in the photos, the product is in brand new perfect condition.
