As Steve and others have pointed out the -1/-1 matrix is a 'tube-cut' and the one to get IMO, for Peppers. For stereo an EMI "One Box" black label is a good way to go. Early thick vinyl and all (I believe) are -1 tube cuts. They sound very close to the 1st pressing and are often in better condition.

Prior to the album’s release, on May 26, 1967, long-playing THE BEATLES The Beatles (Apple PMC/PCS 7067/8) 1968 $8,500 - $11,900+ In 2008, this double album celebrated its 40th anniversary, and it is fitting that The Beatles ranks as the most collectible album pressed in the U.K. Following on from Sgt. Pepper, these four sides of raw, vibrant and downright contrary music still baffle and delight Beatles

This label was lime green and was used until 1971 where it was then replaced by the similar red target label. All the Capitol Beatles albums were reissued on this label, except for The Beatles Story and the three 6000 series albums. Note that this Yesterday and Today pressing is stereo but bears a MONO catalog number. xQm00B. 198 134 118 260 68 281 374 464 318
