Thanks Guys... I already have the Photo Chronicle book. It is nice. Modeldude, I went to the museum and saw the beauty (it's not a beast is it!?), but that was 3 years ago, and they may have that book again, so I'll give it a try.
My problem is that I do not want to build the AMT kit because it is WAY too big for me. I purchased on e-Bay the old Aurora kit, whose size is more manageable, but the kit was designed in '62 before the Valkyrie ever flew and there are some serious mistakes in that kit, which would benefit from having that beautiful drawing that's in the Aero Series book...
