2 very different paintings by the same artist Rory MacBeth. Although they deal with the same issue of perception.
The sterling board is actually a painting. It challenges our notion of reality as it is perceived, and our expectations of how things really are and not how they just appear to be.

Rory Macbeth was once a Street Painter in Barcelona. We met on the street 1988 while he was street painting. That was quite common then, and if you were good, you could make a living doing it. I knew a street painting couple who bought an apartment in Barcelona with their earnings of small change. Rory is brilliant, a technical wizzard painting and phenomenally talented. Now he shows all over the place aside from having been one of the organizers of Pilot, in London, an archive and showcase of unrepresented artists.
