This is the rather odd 1:35 scale Testor's (USA) Four-Star Collector's Series model of the JS-1 (IS-1) Joseph Stalin Tank. This was a heavy tank used in the latter part of the Great Patriotic War to spearhead the offensive into Germany and the final battle for Berlin. The kit has very little detail, but the decals are interesting. The main image shows a polar bear on a red star. The slogan on the side of the turret says "For Stalin".
Hobby House (Ottawa) was
selling off a bunch of these for $20. Lots of fun and I got a display
case! For a Testor's kit it was actually rather good. The box included a large clear plastic display box long enough for the tank and gun, which of course was used for some better project.
