Their self - reflexive but coded titles refer to materials used and basic production details: «S. P.» in S. P. / R # 113 (all works 2013) is shorthand for «suspended»; «R» stands for red, the
color of the acrylic, enamel, or Day - Glo
paint applied to each plate; «# 1,» the
chronological order in which the work of the series was made in a year; and «13,» the year in which the work was completed.
