Question... Looking for a picture

I am trying to find some pictures of my uncle, Bill McHone & my Dad, Butch Scott. Specifically, I want to find a picture that has a sponsor logo on the car for Mac's Lettering (my grandfathers's retirement business). They raced at Big Country (different name back then), Englewood & Lakeside.

Any tips on how to search for this? I want to copy the logo on my Legend car this year.

Thanks.

Scotty
