Motorcycle Awareness: Motorcycles on Stamps covers

Scans of over eighty worldwide stamps featuring motorcycles decorate the top and left edges of these covers. "Motorcycles On Stamps" is printed in a chrome-style font in a grey-green color. In the lower-right, two stamps pay postage: an 8¢ "Stamp Collecting" single (Scott #1474) and one of two 39¢ Motorcycle stamps (Scott #4087 or #4088). Each bears a pictorial postmark reading "Motorcycle Awareness Station" dated May 24, 2016 from Coquille, Oregon.
