Further Accidental Folk-Art: Ether Signposts #45/52a - A Year In The Country
In terms of accidental folk-art, I think these British Rail leaflets from 1970 should be filed alongside the Cornflakes packet that is featured in the Own Label: Sainsburys Design Studio: 1962 - 1977 book by Jonny Trunk. (Although strictly speaking I might say to file the British Rail leaflets nearby to the Sainsbury's Corn Flakes, say under Accidental Folk-Art/Hauntological Precedents.)
