Early development sketches in working process/stages/scenes. I don't know what exactly the process to design was, I would be hazardous to claim these are hand pen drawings, probably are copies after the originals used for brainstorming new ideas/testing shadows/colours. A few of them are indeed hand coloured (you can see the back scans showing the watercolours penetrating the paper). Acquired from a dealer in Osaka in 2021 Among them, there are also sketches for Gundam Tactics figures, quite a lot. Some of the sheets have correcting fluid, indicating these were used by the studio while developing product. Ca. 150 sheets, 37x27 cm but also A4 size.
