I worked a lot on the “Three Brothers” animation, to get rid of the logo; this is my best attemp - far from perfect - with an alternative dub found on youtube, by Chazz Rauenelle

Three alternatives: leave it “as is” (I’d like TO not choose it), find a second open matte source (the best and fast way), or find a crazy person who would like to take the honor and responsability of fix it, frame by frame, using also few images and a bad quality 4:3 version (the only way to get the perfect delogo version without a second source).
