How do you keep unauthorized Klingons, Romulans, Borg, and Space Jackalopes out of areas you designate? The 8'' by 11.5'' Star Trek Starfleet Tin Sign, of course! Letting people know that the follow spot is for Federation members only, the Star Trek Starfleet Tin Sign is slightly more restrictive than normal Federation protocol but then again...maybe you have that Genesis bomb thingy and you don't want people messing with it. You know...whatever!
