http://frankwyatt.com/beatles-posters-where-to-buy/ When The Beatles albums along with Beatles Posters had been very first set on CD in 1987, they had been mainly launched in stereo (although the very first four albums were launched in mono.) This signifies that the mono mixes of albums like Revolver, Rubber Soul, & Sgt. Pepper have been extremely difficult for Beatles fans to hear during the CD era.
