Bob Marley and The Wailers - Waiting In Vain / Roots 7" Vinyl Single

I'm clearing out some old vinyl and have this Bob Marley and The Wailers 7" single. It's the 1977 Island Records US pressing featuring "Waiting In Vain" on the A-side and "Roots" on the B-side. The record shows some wear and has a small name written on the label, but it's a classic piece of reggae history. Comes in a plain white paper sleeve. Used.
