Abstract
Vacuum easel for releasably holding material. The vacuum easel includes a panel having a first sheet and a second sheet with a plurality of walls disposed between the first and second sheets. The walls define a series of progressively larger air pathways between the first and second sheets. A plurality of openings are formed in the first sheet to allow communication of air between the exterior of the first sheet and the respective air pathways. At least a subset of the openings are associated with each of the air pathways. A zone selector is operable to selectively communicate a source of vacuum with at least one of the air pathways to draw air from the exterior of the vacuum easel through the openings associated with the selected air pathway.
