(Raising my hand ...)
SS JOHN W. BROWN is a restored and operational Liberty ship home-ported in Baltimore, one of only two remaining operational Liberty ships from World War II. As was true of thousands of other merchant ships during the war, Armed Guard units served in JOHN W. BROWN.
(Full disclosure: I am a member of Project Liberty Ship, which owns JOHN W. BROWN, a volunteer crew member on the ship, the webmaster for Project Liberty Ship, and a member of the Project's Board of Directors.)
Aboard the ship are three museums, dedicated to the merchant marine, the shipbuilding industry, and the U.S. Navy Armed Guard. While I have no responsibility or authority for that museum, I am confident that the museum would be pleased to have your photograph.
Please contact me privately at firstname.lastname@example.org.
PS: When you say "Freedom Ship" do you mean Liberty ship? I am otherwise unfamiliar with the term.
