Beatrix Potter's Ginger and Pickles (below) is dated 1909. It wouldn't interest a serious collector because it's falling to bits and has some strange brown marks on the pages. But I love this copy, especially the illustrations inside Ginger and Pickles' ill-fated shop, with all the old tins and the tiny drawers behind the counter. It's rather a strange tale, but contains a timely warning about trying to live on credit!
I always pick up old ABC books if I see them, and a recent find was this Babar version.
