Black & white spot illustrations on themese of problem solving via therapy

A series of black & white spot illustrations each one dealing with different aspects of therapy or environments where problem solving can take place. Each greyscale artwork shows two people working together. In the a cafe, with a plant between them, one talks, while the other listens, taking notes. In the park, you have the same relationship of talker and listener. Another illustration shows an empty container either about to be filled with different shapes, or perhaps the container has just been emptied of shapes - possibly symbolising problems. And, in the final illustration, below, you have a balancing of scales.
