Anybody know the background to this little fella that arrived today, cann't find reference anywhere.
Markings are ENTEX Peyo 1982 Made in Japan

He belongs to a lego like LocBloc playset. There are four different sets of them available that you sometimes see on ebay.

Here is a link to the ones I have

Cheers Maureen, must admit I'd never heard of Locbloc before, but yours look like nice sets. Must keep my eye open for them.
