Goodnight Moon

I got this piece of mail from Bryon (the USA). The stamps and stationary celebrate Goodnight Moon, an American children's book written by Margaret Wise Brown and illustrated by Clement Hurd. It was published in 1947.

It took me a while to realise it was actually an aerogram! For once, I managed to open it properly.

I have not read the book (yet?). But I like that, on the stamps, they knit and sleep. It seems a relaxing life!
