We were sad to hear of the recent death of children’s book illustrator Margaret Bloy Graham, who was 94.

Although you may not recognise Margaret Bloy Graham by name, it’s very likely you’ll know Harry the Dirty Dog, her famous character, which she created alongside her then-husband Gene Zion (followed by No Roses For Harry, Harry By The Sea, and Harry and the Lady Next Door).

Harry was originally published in black-and-white. Margaret added colour in the 2002 edition.She won two Caldecott medals and collaborated with several children’s authors, such as Charlotte Zolotow and Else Holmelund Minarik.

Harry the Dirty Dog, published in 1956, is still one we’re asked for all the time. This got us thinking about what a meaningful achievement longevity is when so many brilliant new picture books come out each year, and how much we cherish handing down our favourite childhood stories to the next generation.

So today, joining dear Harry, are even more picture books we have to keep in stock to meet demand 50 or more years after they were first published (with apologies if we’ve missed your childhood favourite).
