:$ When I was a kid, I also used to build the small ones by 青島 Aoishima i.e. 要集齊四細盒才能結合成機械人或戰艦的模型 bought by my father at 舊屋村(七層高)街市的玩具檔 in the early 70's. But, according to my memory, I have never collected a whole set of 4 so far. :( It is really great to see their box art photos (the big sets) again. :64: but I no longer have the passion to collect them lor .... :78:
