“Hanging Garden of I-95” is a 30’x120′ multi-panel collage based on the drawings shown here (top, left and right). The gallery’s website has working photos of the piece’s translation to full color mural. See here.
In the scale-up and conversion to the big, public piece, you lose the hand-drawn quality but gain incredible tropical va-va-voom color. (The enterprise is sponsored by the City of Philadelphia Mural Arts Program by the way.)
In the nearby gallery, drawings used by the artists to create the mural are on display in the back room. In the front space is recent work by the three artists.
