We were proud to promote the Stay Well Event (www.staywellevent.org) as part of a Campaign to keep America safe as part of a Nationwide Vaccination Day in Baltimore, MD. No matter the event, our LED Billboard Trucks put you right in the middle of the action. #nationwidevaccinationday@directadnetworkofphillywww.directadphilly.com#ledmobilebillboards #ledtruck #ledtrucks#digitaladvertising #digitalmarketing #dooh#ledbillboardtruck #ledbillboardtrucks#mobileledtruck #mobileledtrucks
