what up

On any given Saturday, the roadsides and medians are full of signs pointing toward garage sales in every direction. This morning I saw a neatly hand-lettered sign along Middlebrook Pike advertising a "G-Sale." Of course we assume that the G stands for garage. What if it didn't? It might have been a garden sale, a garbage sale or a gun sale. My son suggested that it could have even been a gnome sale. If the sale were especially big, how would this family advertise a combination Garage And Yard Sale?
