Sobrantes 2012 from Rosa Gravino

Definately Gotij great, beautiful inspiring mailart from Rosa Gravino! A relic of stunning asemic visual poetry. I'm never sure if you open or don't open but I had to see it all, hold it out of the cellophane and I have slipped it back inside again. It is gorgeous and if only I didn't have to spend the next two days with classes of enthusiastic (wonderful) children... if only I could follow up with some experiments that this piece has suggested! THANK YOU! 
PS: Sobrantes means leftovers, I think.
