It’s incredible what you can find in a second hand bookstore in Hastings. A while ago I picked up an old copy of the 1966 Internation Film Guide from one of these bookshops (it’s so old you can see on the cover that it was published back in the days of shillings and pounds before British currency was decimalised in 1971.)
It wasn’t until fairly recently that I got around to scanning the animation sections of the guide, which is an interesting window to the British animation scene of the 1960s, featuring a showcase of work from Halas and Batchelor, Richard Williams and Bob Godfrey.
