70's K-tel "Disco Nights" and "Disco Rocket" 8-Track Tapes - K-tel Compilation

One 8-track features "Disco Nights" from 1979 and the other "Disco Rocket" from 1977. Both are K-tel compilation tapes. Both 8-tracks look to be in very good shape, with some very light to the plastic cases (mostly the white one) and a name in ink on one of the paper covers. Please see the pictures for details. I have not played them through as I do not have an 8-track player. These are being sold "as is".
