Ancient Maya graffiti went from being thought of as "crude scrawls"of squatters to "folk art" produced by Classic Maya elite artists but no two drawings were ever alike.
Three pairs of graffiti found both at Rio Bec and Holmul (sites separated by over 130 kilometres (81 mi)), with similar quality, and technique, possess such similarity in design, down to the smallest details, that they are almost certain to be the product of the same untrained Late Classic artist.
