I have an add-on to Acrobat that can usually strip the Google logos off in under a minute. If you could post links to the files that need to be sanitized in this fashion I take care of them and upload them to Mediafire for you to grab.
Fynnjamin not related to the Google logos, but the bogus copyright claim on the file you uploaded here on the first page needs to be cropped out at the bottom of the page. She doesn't own the copyright of the work anymore because the piece itself is public domain. I just removed the claim and reuploaded a new version, please remember next time before uploading to remove the claims.
bother again. I don't have a way to remove it once I've made the images into a PDF. The scan quality is pretty poor anyway for the volumes those pieces are in on archive.org
