That's the very things, Artoo_Detour.
They made a huge re-appearance in the UK around the time of ROTJ. It seemed as if every store had cardboard stands full of them. And they sold too due to their cheapness.
Thanks for the info, dcarty. It looks like getting one isn't easy. Which is weird - when they came to mind recently I assumed there would be a few of them up for sale. I was expecting 'somebody clearing the attic' type sales rather than collectors/ traders due to the sheer volume there was of the things. But ziltch!
Arguably the best thing about them is this bit of artwork which - unless I'm mistaken - shows Obi-Wan with a cameltoe!
I remember this picture being on the in-store stands despite being far too young to make cameltoe jibes at the time!
