I found this the other day rolled up into some of my old artwork. We are in the process of moving and finding all kinds of...erm, treasures tucked away in nooks and crannies. This must have adorned my bedroom wall some 30 years ago. Did I do this? Did my boys? W's guess is that Uncle D (my big brother) did it many years ago to torment me. He is quite likely right. ;-0
Just had to share in case the poster might bring back any fond memories for someone else.
