I recently was able to acquire this from Mandarake via my boyfriend and wanted to share the character settei from the cancelled production of Terrahawks. Yoshikazu Yasuhiko was originally on board to create the concept art for the show that eventually became the Terrahawks many of us know by Gerry Anderson. Originally penned in 1974, the show would have been an SF anime titled Terrahawks: Order to Recapture Earth. Ultimately the show was cancelled due to the TV production company MBS not needing any SF anime at the time. Design elements from these concepts were then used for the concept designs for Freedom Fighter Gunboy, which was penned in 1977, which in turn became Mobile Suit Gundam in 1979. Technovoyager also got some of the mechanical designs (which I have not processed yet), versus the character designs.
This book was heavily yellowed and my scanner is what it is, but I did what I could to preserve the line quality of each drawing. I don't do this professionally, but I am trying to archive the best that I can.
