The Bottle Hammock was actually something that an acquaintance of mine had invented. It was basically a strap that you could use to carry bottled water. There really wasn't anything like it back in 1991 when he invented it. He hired me to come up with a character for his promotion and packaging. What I came up with is the water bottle character seen here (the label on him says "H2O") relaxing in his hammock. This illustration was done in pen and ink and was used for his logo.
