"Just do it later"

.In this district of central Paris a mural representing Tintin and Captain Haddock appearing to kiss each other on the mouth, a road sign and a woman with "just do it later" ....

Strange connection in this Parisian street photo between a mural of Hergé's heroes, a woman in a black "just do it later" T-shirt and a prohibited sign pointing towards the fresco. Finally on the left a black courier going about his business; Does all this have some hidden meaning?
