Thanks for making me smile Prof!
As I was scrolling from the top I was thinking about my copy of 'By Space Ship to the Moon'. I bought it at a school fair in the 1990s as Pratt's images (the book's from 1952!) remind me of drawings my father did in the 1960s when he was at university. He colated them in a scrap book with newspaper and magazine articles from the time.
Space travel must really have blown people's mind back then (hell, it blows my mind now to think what we can do when we're not killing each other...).
