A lot of our old family piano music (popular songs and show tunes of the day) which I inherited from my grandmothers, or else found in secondhand shops, gave guitar/banjo/ukulele fingering diagrams, often with a chord symbol but not always. It dated from before the days when music reproduction-technology really took off, and sound quality was pretty low; so much of its use was live - dance bands, vaudeville etc - and sheet music sales were more of a thing than now. I'm not sure when that practice got started, though. But I have certainly seen it in early 20th-century stuff.
