Wolf O'Donnell: WW1

I tried sharpening the colors up, which were distorted in the scanning, to no avail. It was done on the back of a handout, so there's writing on the other side which can be seen.

Meet Wolfgang O'Donnell....lol (although O' means "from" so he would probably be Wolfgang *von* Donnell). WW1 pilot version of him. Did this is trig class.
