SPACEMEN - MAKER? - ITALY

A range of unidentified small hard plastic spacemen. These quaintly old-styled astronauts are about 1.4 inches tall. A maker has yet to be identified, as has the sales method. They may have been premiums with sweets, but nothing has yet been confirmed. The plastic used does vary slightly and the details of the sculpting suggest that they were re-issued from different molds. Details?
