1906 air mail

My 102 yr old neighbor gave my wife a box of postcards. The oldest is 1906 and the newest 1937.
In the lot is a picture post card of a Wright flyer with a pilot sitting in the machine and a 1900 dressed lady looking on.
The back of the card says"mailed in the air " "By Aero Post from the Avaition Circus Jun 6,7,and 8 1912"  The 2cent stamp is cancelled with a Wright Flier imprint.
I would love to post a photo, but still can't figure out how to do it.

One last (?) item:
I found the bio of 'your' pilot, Lincoln J. Beachey, most interesting.
