Bloomberg recently teamed up with Artnet to analyse the sale prices for the works of around 1,000 artists (living and dead) in order to determine which artists’ works were increasing in value the most.

Cleveland based ‘first generation’ Op Artist Julian Stanczak came out 6th in their analysis with his works increasing in value over 3,000% over the last 12 years.

Stanczak was one of the artists who was featured in the groundbreaking ‘Responsive Eye’ exhibition that really brought Op Art to the attention of the mainstream in the mid 1960s.  He is currently 81 years old and is still painting. He lives in Ohio with his wife Barbara.
