Old Star Frontiers figs come up on the TMP Space Ship thread often, along with discussions of 'lead rot'.
I've still got several sealed boxes I'm a bit scared to open.

I pointed out on TMP the Sathar's sleek, rounded forms suggest late 50', early 60's sci fi, certainly apropos to War Rocket and the like, while I suggested the Fed capitals were positively Cavor-inspired, or so they looked. Nothing that would look out of place for Space 1889 ether ships.
Does the original art ever come up for sale? I'm a sucker for same, with a fair collection of original Traveller and other RPG drawings.
