Cao Cigars on Paintings

I was at the mall today with my aunt and cousins to buy something. We arrived at the place around lunch time and we directly went to a restaurant to eat. We noticed there was an event going on at the atrium so we decided to stop for a moment to see what's going on. There was an art show. Paintings from different artists all over the city were displayed. We moved on and ate our lunch.

After lunch, we decided to go back and see more of the paintings. I particularly liked one of the displayed items. I think it was more of a slight abstract painting where the subjects are cao cigars and its smoke was in a human-face shape. We were not really allowed to take pictures so I cannot show it here. It would have been great and you would understand more about what I am talking about here when you have seen it but nevertheless, I really liked that painting. It was after the event when I knew that the one who painted that was one of my college professor. Very clever.
