If you visit Shepard's website, Obey Giant, this note is the artist's response to requests for more prints:
Thanks for all those who bought the print in support of OBEY and OBAMA. Unfortunately, the print is sold out and we do not plan on producing another edition. The edition was released earlier today with great response. The PROGRESS screenprint was exclusively available through OBEY and the HOPE offset print will be distributed by the OBAMA Camp as an awareness campaign.
I believe with great conviction that Barack Obama should be the next President. I have been paying close attention to him since the Democratic convention in 2004. I feel that he is more a statesman than a politician. He was against the war when it was an unpopular position (and Hillary was for the war at that time), Obama is for energy and environmental conservation. He is for healthcare reform. Check him out for yourself www.barackobama.com. Proceeds from this print go to produce prints for a large statewide poster campaign.
The artist's original edition of this work was 350, unnumbered and unsigned. Various copies of the print are available for auction all over the world at various prices, for a number of reasons. Depending on the success of Obama's reign, the value of the print will continue to soar and it is, without any question, already more historically significant that any headline-bearing newspaper announcing the changing political guard.
