Colored Heroes, Valley Forge Map and a Transistor Radio

What are the details behind the heroic acts pictured in a poster about two African-American soldiers in World War I? Senator Charles Schumer (D-NY) helps find the answer. Then, is this a hand-drawn map of Valley Forge that George Washington used during the American Revolution? And does a Tucson man own one of the first transistor radios ever made? Finally, after 70 years, a Washington man wonders whether a business card ties his father to Prohibition-era underworld crime.
