What To Look For In Autumn (Ladybird Nature Series No. 536, 1960), at Archive.org. Not the best scan, being too dark, but free.

Also What To Look For In Winter (poor scan), Spring (poor scan) and Summer (scan is good, but too light). Long out of print, but these editions seem very common on eBay if you want the real thing. The content hasn’t dated, other than a few farm scenes (‘axes rather than chainsaws’, ‘hop-picking by hand’, and some ‘fancy hay-stacks’). Possibly a nice Christmas present for someone, all four in mint condition?
