As promised, here is a bit closer look at the three 150-piece HG Godzilla puzzles from 1978. The first one is the "red" one, also known as "City Rampage" (although you won't find the name on the box, if I remember correctly, and mine is out of reach at the moment). The name may have come from HG Toy catalogs, but who knows. The most we can be sure of is that they gave it the number of #458-02.
