A portrait artist draws while on LSD… for science! (1950s)

From the Daily Grail:

An artist –whose identity has been lost– was administered two 50-microgram doses of LSD, each separated by a lapse of one hour, and was then asked to draw portraits while under its influence, using the doctor who administered the drugs as a model.

It is believed these artworks are part of a study conducted by Oscar Janiger, a University of California-Irvine psychiatrist known for his work on LSD, which started in 1954 and continued on for the next seven years.
