Very cool poster! Back in the early 1990s, the Trek merchandise company Star Land sold a fantastic caricature poster based on the same concept: every main and guest star from TOS. The art style was heavily based on the work of Mort (Mad Magazine) Drucker, and was pretty large. Since that time, I have not seen one reference or image of the poster online--not even eBay, the official ST site--anywhere.
If anyone knows which poster i'm referring to, and have an image to share, please do so. It would be quite relevant in this thread.
