It’s interesting how books evolve sometimes. At left is the initial cover proposal I made for Perk Up. At right is the final design for Coffee Time that the publisher put together.
By the way, did you know that World War I soldiers would often refer to coffee as a cup of george instead of a cup of joe? The term came from George Washington’s, the exclusive brand of instant coffee used by the U.S. Army (it was named for its Belgian-born inventor, not the president).
