This work is called Heath of the Brandenburg March and was painted by Anslem Keifer.
The artist decided to use as a medium a mixture of oil paint, acrylic paint and shellac, creating a non-linear, yet vivid and expressive representation that had the capacity to transmit a strong feeling of instability, anguish and discomfort, but showing a twinge of courage to overcome all these things.
C and D. Pop art has many vibrant colors that are used on many pop culture idols. For example, Andy Warhol does many pop art works. Look him up if you want :)
