Who did this?

20130119drawingsWho did this? Are these the crazed drawings of a deranged person? Or is someone trying to tell a story? Or both? No one knows. Vendors at the La Penitence Market said that a few days after completion of this bridge at Sussex Street, separating La Penitence from Charlestown, these drawings appeared. They said they went away one afternoon and left it clean and came back the next morning and found the drawings. (Photo by Arian Browne)
