People say “do not underestimate the strength of mass people”. This expression might be correct to apply for this artwork, which created from mass people.
An Atlanta-based artist, Craig Allan, illustrated portraits of famous figures from formation of hundreds of people. Those people neatly arranged and formed many famous figures, from Marilyn Monroe up to Liberty Statue. Craig will then photographed them, and these photographs sold at $50,000 each. He generated this idea when he was taking photograph the crowd down below from the sixth floor of an apartment of her mother’s in Alabama. He visualized the crowd captured in his lens as an eye formation. This was the point he started this creative effort.
