One of the things I routinely do is design book display signs for the library. At the Main Library there are multiple displays and they rotate on a monthly basis. Due to the sheer volume of sign requests, I simply cannot spend a ton of time on them. So if I do come up with a graphic or illustration, it is generally something I can produce quickly. Like the simple lines that made up the grass in this sign. Doesn't it just say "summer" to you?
