The blog AltJapan has reported on a momentous find for mecha fans. Anime fan Roger Harkavy has discovered a box that belonged to Imai Company that contains artwork from Artmic Studio. The box contained black and white production drawings for Genesis Climber Mospeada and Super Dimensions Cavalry Southern Cross.  He has made the file available to mecha fans everywhere.  AltJapan has the full report. You will certainly want to download the PDF and take a look at the designs that almost made it into Mospeada. I was fascinated by the rare look into the show Southern Cross was originally meant to be.
