Adrew Biggio’s basement has been converted into a museum-of-sorts with display cases of war memorabilia, artifacts and other keepsakes that he has collected since serving his tours of duty as a US Marine in Iraq and Afghanistan.

Biggio, who founded the Boston Wounded Vet Ride that would roar through East Boston and Revere every year to raise money for wounded vets, is busy organizing a countertop stacked with autographs of the 22 World War II veterans that have been immortalized in his first ever book.
