Tracking Logo Planes and Special Liveries

I am an avid railfan. Some railroads have painted certain locomotives in special paint schemes to pay tribute to their heritage. I know some planes have this, as well as honoring local sports teams. You can track the heritage units at www.heritageunits.com . Does anyone know if there is something similar for these planes. If not, can someone try and post the tail numbers for as many special planes as they can. Thanks!
