Sale @ TeePublic!
The top row, from left to right, are from Congo, Congo and Westworld. My “TraviCom” shirts are replicas of the shirts worn by the ill-fated first “Blue Contract” team in Africa, as seen below:
The Westworld shirt is (apparently) the logo of the Delos resort, though it certainly does not get much screen time. You only see it in the intro film on the hovercraft. Note the division of the circle into three segments, like the three themed areas of the resort.
The bottom row are more recent shirts, but not brand new.
