The poster is a rare proof printed on thick paper, possibly Arches. Printed before the colour registration marks on the right margin have been removed. This proof has also been hand signed in pencil by Peter Blake ‘To Ceri from Peter Blake’ . It features an artwork created by Peter Blake, a collage with watercolour. The poster was designed by Gordon House and printed by TPS London. The sheet does have some very light browning in the lower left corner which is more obvious when held up to the light, it is barely noticeable on the surface. The sheet is not pristine as it is over forty years old. Slightly larger than the poster, which is 76 x 51 cm (30 x 20 inches).
Sheet Size 90 x 58 cm (35 x 22.5 inches)
