In The "GP3 Teamart" section, I have uploaded my recent versions of Team Artworks for those seasons: 2020, 2001 and 1994. It's for GP3 1.13 and you will need GP3 Edit to put them in the game.
You are right..... I have uploaded them yesterday morning (2020) but 1994 and 2001 last sunday so maybe they will be there today. If not, i will upload again. Thank you and i'm happy to ear from you too .
