Ok, here's the story: Back in the spring of 1990 I was stationed in Norfolk, Virginia. I had a weekend off so a shipmate of mine (who's still my best friend and is here in Houston as well) took a trip up to D.C. While there I went to Virginia Bader's Fine Arts Gallery. They had this print and I bought it for $145 unframed. While the salesman was getting the print I also saw a print by Mike Wooten of a 109E-4 from the Battle Of Britain. They wanted $45.00 for that so when the salesman came back I told him that I would like a copy of the Emil as well. He told me that he had a special one that he'd sell me for the same price, the only difference was this one is signed by Mike Wooten AND G. Rall, D. Hrabak, and A. Galland. He went back to the stockroom and came out with it, unrolled it and I saw the signatures on it. Needless to say I was smilin' like a possum eatin' a sweet potater. I have it framed and hanging on the wall next to the Hartmann print. I'll take pictures of them later and post them here.
That print (the white Hartmann 109 by Jerry Crandall, Hartmann wasn't a painter, not that I know of) hasn't been available in over 15 years and it sells for about $2000 now on the secondary market.
This is someone else's copy of the same Emil print...you can just see the signatures on it.
