Actually cardboard cut-outs were quite popular around that time. I very much enjoyed 'In The Looking Glass' which used that technique and a short while later 'Jane' did the same.
Ah I notice 'Gulliver in Lilliput' won a Bafta for graphic design. Graham McCallum also won it for 'Jane' in 82. I'll have to check whether he did 'In the Looking Glass'.
