Zack,
I am also a 56th FG enthusiast. I happened to attend an art show at an aviation shop in a small town here in Oregon back in 1993. I had heard there might be one or two WWII fighter pilots there, so I took a few Joe Milich prints that I had, along with me to the show.
When I got to the shop there were only a couple other customers there, but standing over in one corner I spotted two older gentlemen talking to each other. I walked over to see if they were WWII vets, and was shocked to find out the two gents were Hub Zemke and Gabby Gabreski!!
I asked them to sign a couple of P-47 prints I had with me, a likeness of one of the prints is shown below.
I also had Hub Zemke sign a Milich print of a P-38 I brought. You may remember that Zemke took over as C.O. of the 479th Fighter Group after he left the 56th F.G.
When Hub first became C.O. of the 479th they were flying P-38's and later transitioned to P-51's.
Anyway, I feel very lucky to have had the opportunity to meet and talk to two great legends like Zemke and Gabreski. And because I just happened to bring along some of my aviation prints, I was able to get signatures from those two gentlemen that I can enjoy for many years.
Ted
