May Day (and a book)

We are May Day today, which as a date is pretty self-explanatory. To mark the first day of the month, I am sharing a picture I already shared in 2024, taken from What to Look For in Spring, one of Wolfie's books. As my son grows up (way too fast for my taste), he is less interested about these books aimed at younger kids than I am. So I reread them regularly. In this instance, every spring. You could say that I don't use a calendar to mark the passage of time, but books, since I read seasonally. Anyway, notice in the text the mention of maypoles. I have been looking for them for at least a decade. No luck so far.
