This piece is called Gravity. It was inspired by Einstein's theories about gravity and distortion around heavy objects in space.
Paper: 160 gsm acid-free archival quality paper.
Backing: Mountboard (unaffixed)
Dimensions: 21cm x 21cm
Framing: I recommend a shadow box frame, or dual glazed frame (where the back and front are either acrylic or glass) to allow the map to cast shadows and come alive on the wall.
