Hi Everyone!
My name is Speedful and Beastiful Leon i'm a Polish fan of F1 since pre-Kubica childhood in 1997 when Williams-Renault and Jacques Villeneuve amazingly dethrones Michael Schumacher and Ferrari for the F1 title with unexpected fall of Damon's Hill form when he drive on Arrows-Yamaha (I loved Arrows-Yamaha 1997 colors with cool Zepter logo when i was cub).I love drawing f1 cars and i have found identified and unidentified some unknown sponsors of each F1 car thanks to Flickr , Motorsport.com, Bridgestone Motorsport archive and other personal f1 websites and us from grandprixgames.org . I'm very happy for quickslick's to Excalibur's post about Rothmans racing logo and Reister Merchandising logo one of sponsors of Williams-Renault used for Japanese gp with Prosieben. I have complete full list of post-Hype Energy drink flag sponsors of Williams-Renault for 1997 season (sadly Hype Energy drink withdraw from Australian Gp to French GP but team gains pricefull victories in this season)
British Gp-Snap-On tools
German Gp-Burg Wächter and Point S
Hungarian Gp-Falke
Belgian Gp and European Gp -Auto Motor und Sport
Italian Gp-Pagine Gialle(non-bold Gillette font )
Austrian Gp and Luxemburg gp - 3com
Japanese Gp-ProSieben and Reister Merchandising
If you want to find logo you can find in google.com simply write sponsors name and see!
Let me know if you have time, I'll be back when i have time for more identified unknown sponsors of F1!
