I lived in the mimeograph era, but was too young to have anything to do with blueprints (other than seeing some under my Dad's arm when he was going/coming to/from work. I remember, though, always inhaling deeply the fumes on the mimeograph paper. Was that the same (ammonia), or was that aclohol? I just remember the "huffing" and not the identity of the fumes.
