F. Schneider in Germany uses recycled cardboard,
and this one came with a corner missing...
it arrived safely and with a great fun portrait.
Added pieces on address side are fun too:
careful with future collages. Me thinks the UHU stick glue
did not hold up as well as its relative:UHU liquid glue:
The World Sticks with UHU! (me too in future mail art :-)
This second sending had a small paper card inside:
Thanks for all!
