Mermaids Cup Sea Sponge Paper PrintMermaids Cup sea sponge Original Artwork by Jo Bell paper print. This pen and ink drawing is of a sea sponge that was washed up on the beach. I was drawn to the beauty of its interesting and delicate shape and loved its designs. I couldnt find the correct name for this particular sponge. But loved the idea of it being a mermaids cup. All prints are printed on Hahnemuhle German Etching paper 310gsm. slightly textured to replicate the original artwork.
