Writing on the Wall

Here's a piece I recently finished for a Quilts on the Wall challenge.   The theme is graffiti and my piece us called Lascaux21.   Much of it is from photos I took at a skate park in London; other bits are pix I took of an array of scribbled writing on one of the shrimp trucks on North Shore Oahu.  Then I cut some screens with my OWN tags.  Can you find them???  After all the printing I both embroidered on it and appliqued "peeling paint" made from fabrics I painted heavily with oil paints and which took AGES to dry.
