"These stunning bird sketches by artist Mark Powell have been done on vintage envelopes, giving them an antique-like appearance. These lovely avian envelope illustrations are extremely detailed depictions of beautiful birds in flight.  Some of these intriguing envelope illustrations still have stamps stuck to them, along with names and addresses, which makes these art works all the more interesting. The off-white color of these old school envelopes give these pictures a vintage vibe, which is visually very appealing.  Powell sketches a wide variety of different birds on these browning envelopes, including owls, humming birds and sparrows. These peculiar and pretty art works turn peoples old junk mail into fantastic works of art. Envelope art offers an interesting way for artists to recycle their old paper products."^^<http://www.w3.org/2001/XMLSchema#string>
