Thank you for your response and your interest in putting Benjamin Banneker's mural back on display in the museum dedicated to his achievements. My best contact on the status of the mural is George Fish, Maryland House project manager for the Maryland Transportation Authority. http://www.bizjournals.com/baltimore/news/2011/12/01/maryland-plans-to-award-travel-plaza.html
George's phone number is 443-829-6727. His email address is gfish@mdta.state.md.us
 He should be able to give you an idea of the status of the Banneker mural. Please keep me updated on your progress and I would be glad to assist you in any way.

Best,
Robert Register
