Aha!! It is the Artist in Seine's creation of wooden rings:
on a real TrashPo ice cream container's lid!
and not destroyed through the mail and postal machines :-)
It did come protected in a recycled ChocoPo Xmas box I had sent Dean:
with wonderful postage and also inside was a little packet of stamps! Unfranked Greek stamps
...to be recycled as well :-)
and a few portrait artistamps:
Thank you, Dean!
Happy to see you in the mail, yay!
