ROBOT aka DIRECTIONAL ROBOT, GREEN VERSION - YONEZAWA - JAPAN
Pale silver green tin battery operated skirted robot. Advances with bump n' go action and lighted eyes and red dome light. The dark blue box was designed for this green color version.
A distinguishing feature of the green version is the position of the two tabs on the lower part of the skirt: on blue version they are they are close together, on the green they are much further apart. The base plate - just visible - is green (rather than black and this version also lacks the stamped detail on each shoulder.
Circa 1957
