First issue hardbox from 1962. Jack Leynnwood box art. Jack primarily did Revell artwork, but since he was freelance, he did others as well. At this point, the XB-70 was planned for production, so the kit is called the B-70 and the artwork shows a winter night-time quick turn around of a SAC B-70 while another Valkyrie roars overhead after takeoff. Very large kit with 6 detailed General Electric J93-3 engines, landing gear and clear canopy.
