Looking through folders and portfolios I found this cut out transparency. The watermarks are from a clear plastic that I use to protect them until they are ready to be framed.
In reality, the frame of these works is part of an ongoing discussion: how and where.
Some of them, when framed, lose a certain fluidity, especially they lose the shadows and the color changes that they produce when they are crossed by light during the day unless they are located near a source of natural light.
Windows, doors and walls are still the way to go.
