Vacation on Venus was my first book, a graphic novel. Yes, I tell you, I was certain I'd become a writer. Or maybe a fashion designer.
Rocketships in the Fifties and early Sixties! Woo hooo!
This particular creation was a (ahem) simple illustrated story made of paper and crayons, a gift for my Grandmother. After she died decades later, my sister and I each received one of her music boxes as remembrances. When I opened the lid, I found my little book inside, which she'd kept all those years. Just a few crude scribbles, pictures, and a dedication, but it was created by her first grandchild and meant something. It means something to me that she kept it.
There must have been several old B movies that fed into my young mind, helping germinate the dazzling idea of going to another planet. But the only one I can remember specifically was Journey to the Seventh Planet, which our family saw together at a drive-in movie.
