This is a series of collages, sold individually.
The image shows 'Plate III'. The others in the series can be viewed at https://www.instagram.com/p/BSBccLeFEFt/?taken-by=heraldblack
They are the reverse of a collagraph plate after it has been used for printing. I was unaware of all the overlapping marks left on it until printing was finished.
The collage is mounted on A4 foam board (21cm x 29.7cm). Unframed.
