Currently on eBay is a vintage Greek “Biscuit Card” featuring a simplified artwork replicating an internal-detonation nuclear pulse rocketship illustrated by Frank Tinsley.

I’ve never seen the biscuit card version. I’ve no idea if this was a local Greek production, or the card was published in multiple languages.
Here’s the biscuit version:
Here’s the Tinsley original.
