Does anyone recollect them? I bought a book on darkroom techniques in an used book store. The book came with a vinil bag that contained a 5x7 RC print and an original FP4 (not plus) negative in a small glassine sleeve. There is also additional info given which reveals that the film was developed in ID11 stock, the photo was taken with a motorised Nikon camera and printed on Ilfospeed Multigrade glossy paper. The photo is of English countryside with a house and a human figure (a fisherman) by a lake. It's purpose I guess was to show novice photographers how a properly exposed and developed negative looks like.
