found out that it was the 40th anniversary when studio shaft released a video
unknowingly I had Shouji Kawamori signed my 1st edition MP-3 Starscream that he supervised at AnimeNYC, even though he's more famed for his works on the Macross series which I do have a fair amount of books; I'm a longer fan of Transformers and glad that I chose the toy for him to sign especially with this milestone for the year
