1960s REVOLVING GYRO-MIRROR in Original Box

What a fantastic piece of 1960s (useful) kitsch.
A spherical mirror which can be opened up to find the stand inside.
Once on the stand the mirror can be moved in any direction you like..
Up, down, sideways..
8cm across and aprox 11cm tall once on its stand.
I just have a few, in their original boxes and some have slightly corroded mirrors - you can see examples in the last picture - I've listed and priced them accordingly.
