Cerne Abbas, Giant, Tump - Original Erching by Joe Tilson - 1976
By Joe Tilson
Located in Roma, IT
Cerne Abbas, Giant, Tump is a colored etching on rosaspina Fabriano watermarked paper, realized in 1976 by the English pop artist, Joe Tilson.
Image dimension: 38.5x18 cm.
Hand-signed, dated and numbered in pencil on lower margin. Edition of 100 prints. In excellent conditions.
From the Wessex Portfolio, a collection of seven etchings with aquatint and six screenprinted poems on rosaspina paper by Joe Tilson.
This contemporary original print represents the Cerne Abbas giant, the figure carved on the slope of a steep hill. This giant naked man is located in England, near the village of Cerne Abbas, north of Dorchester, in Dorset. The engraving, 55 meters high and 51 wide, is formed by a trench 30 cm wide, 30 cm deep, made by tearing the grass and digging the earth up to the underlying plaster. In the right hand the giant holds a 37 meter long club.
Composed by three different etchings, each olf these titled on the right margin, this is a very interesting contemporary artwork not to be missed for your home collection!
A copy of the same print is preserved at the Tate Gallery.
