I think the message (if there is one) is the contasting image of an "art buff" a term which implies an expert in appreciating visual excellence and stylish flair, in flat sensible shoes, what looks like a quilted jacket, and with a distinct stoop to her elderly and no-longer-stylish shoulders, listening intently to a commentary about a boring battered pillar standing in front of a cracked and discoloured wall with a shapeless smudge on it. If there used to be anything of artistic merit hanging there, it is now gone, and all that is left of it is the commentary.
But equally, it could just be a drawing of someone admiring a plinth from the age of antiquity. There doesn't have to be any subtle meaning to be winkled out.
