If you've got a physical, but limited, store frontage, there's no excuse not make the most of it.
I spotted this fabulous little example in Byron Bay. It's a sky dive business and the ONLY store frontage it had was a staircase - the whole business was upstairs.
So not only had some bright spark decided that some eye catching colour was needed. They took it a step further and got zero budget marketing creative. They've painted various ascending heights on each of the steps.
