The plane flew 852 feet in 59 seconds. One stamp shows Wilbur and Orville Wright and Flyer A while the other stamp shows the Wright brothers, Flyer A and a shed. The picture below shows a full sheet. This sheet is as fresh as the day it was purchased at the post office 40+ years ago and is suitable for framing. If you're a stamp collector, it is Scott #C91-92. Plate# 38860 LR.
For First Class, flat shipping with a stiff cardboard backing for mint sheets I charge a flat rate of $4.00 for items purchased with one payment and sent to US Addresses. That covers as many sheets as you win, so bid on several and save on postage.
