Last year I saw these on Ebay.
Nice red LP astronaut clones issued as a carded blister set by Langnese Alpha Star.
I looked into Alpha Star.
It was an ice lolly available in Germany around the end of the Seventies and start of the Eighties. The plastic figures were part of the advertising campaign. I assume they were sold in ice cream shops and kiosks but I'm not sure. Anyone know?
The advertising for the lolly also included:
kiosk price lists [Alpha Star bottom right]

Brand posters
even packs of cards!
and a modern Perry Rhodan magazine cover!
Alpha Star landed in Italy too.
Here's the Gelato brand poster.
Have you come across Alpha Star?
