Here are three pieces of art taken from North American Aviation documents from the early 60’s, part of the Spivak collection. Not the best reproduction quality, but whatryagonnado. The two with downturned wingtips depict the B-70 as actually built; the other is slightly earlier, with some differences from the final configuration. The most obvious is that the vertical fins have leading edge extensions; additionally the forward fuselage contours seem off, though that might be an artistic flub. As well, it does not appear to depict the existence of the wingtip fold hinges, which is either a mistake or artistic license for some purpose.
