Oil paintings increase in value as time goes by.

As the memory of an individual fades, that person's life remains more vital when observed in an original oil painting. Oil paintings mature through the years and become more valuable, both financially and personally. Think of what you would give to own an oil painting of your great great grandparents, and how rewarding it would be to look upon the images that you emulate. Rest assured that most oil portraits take a position of major importance in a family and are seldom lost or destroyed.
