Preferably, use a perforating wheel to cut,
but in lack of such, you can cut along lines with a scalpel,
taking care to not cut all the way to the edge.
The original private view invitation for Hockney's show at Kasmin Limited in 1965. A dye-cut forms a frame around his work ""Hollywood Swimming Pool"", inspiring if you like Hockney and also for the production value. Good condition. This is not a common thing. Slight glue residue on the top right but does not decrease the beauty of the piece, rather it shows the producers hand.
