Thank you very much for viewing. This is the Carl Fischer edition of "Arban's," one of the most famous trombone method books. I purchased it about 20 years ago and practiced with it frequently, so it's not in the best condition, with stains and folded pages where I used it as a bookmark. However, there are no markings inside, and the pages are clean. It's originally quite thick, so I think it would be fine to copy or scan only the necessary pages for carrying around, keeping the original at home. Please, give it a try. I believe this version is hard to find, so please consider it at this opportunity.
