Petropetal defies the postal strike!

According to Cheryl Penn, there is (or was) a postal strike in Kwazulu Natal.  when I sent my mail art it was with a certain sense of defeat.  So, that I received this dynamic mail art from Petropetal has cheered me. Petropetal's envelope is a folded taped affair.  There is no inside as we know it. What I mean is it doesn't close or open, it just is. It measures 21 x 8.5 at its longest width. I never know if you can tape over stamps so they won't fall off.  Petropetal has and nothing terrible has happened! thank you Petropetal!
