She also commended the "hard work" that went in to making the "beautifully-bound book", which contains pictures of Leopold kicking back with a cocktail, posing with a cactus and having a nap with a mystery toddler.
The book ends with some sage advice: "Remember: adventure before dementia!".
Leopold, unusual though he is, is not the first gnome to set off the open road: the travelling gnome prank dates back to the 1980s, and there is even a Garden Gnome Liberation Front, dedicated to the purpose.
The idea was also brought to the public attention in French film Amelie, in which the eponymous heroine steals her father's garden gnome and sends him round the world, in an attempt to inspire her depressed father.
The idea of placing whimsical characters in exotic locations throughout the world is also a common trope on Instagram, where the adventures of plastic dinosaurs and stuffed toys attract thousands of followers.
