Mario Maala

While his LinkedIn says he worked at Daydream from 11/1979 - 8/1984, it's believed he worked for one week in 1978 to paint Boba Fett's armor. This would pair it with the PP2 and ROTJ costumes.

According to Boba Fett historian/cosplayer boba87fett, after speaking with Mario, he believes "[Mario] painted the PP2 Kenner photo shoot costume, one of the original touring costumes that had what became the RotJ hero helmet and an additional touring costume with what’s been called the 'Sandy' helmet historically."
