The difference now is the same label, Acrobat Music, is releasing this "Best of the Singles" album on LP.
There's hardly been any Kingston Trio releases on "vinyl" except for 2 reissues that I'm aware of:
(1) The Best of The Kingston Trio [Delray Records]
(2) College Concert (LP cover: NBD) [Vinyl Passion]
They used the same picture from the KT's "String Along" album for the cover.
