Deep Purple – Deep Purple In Rock

This is the first UK issue

The main identifiers are:

- Laminated gatefold sleeve with 'Printed and Made by Garrod & Lofthouse Ltd.' (until about 1981)

- Inner sleeve: Copies bought in the first month of release feature a plain inner sleeve with 'Patent Nos. 1125555' text and 'Made In Great Britain' text in BLACK PRINT near the bottom on 1 side. Shortly after this LP was released (about July / August 1970) EMI introduced the 'Harvest' advertising inner sleeve. So with all copies made from this date onwards mostly having the 'Harvest' advertising inner sleeve instead. However, plain EMI inner sleeve were also used;

- Runouts: A2 / B1 (until about mid-1975). It is worth noting that variant 1 - 1st pressings with A-1 / B-1 matrixes are extremely rare on this LP. They were changed prior to the release date, with even most release date copies having A2/B1 matrixes instead. Only 1 in 20 1st pressings have this matrix - with A2/B1 matrix being used through all remaining 1st pressings, and many 2nd pressings also;

- The upper rim text begins with 'THE GRAMOPHONE CO LTD.' (until about May 1974);
- No 'EMI' logo on labels (until about June 1971);
- The inscription 'MADE IN GT. BRITAIN' on labels is separated of the lower rim text and centered above the circular bottom line (until about May 1974);
- Song listing in 3-lines for side A and in 4 lines for side B (until about the second half of 1972);
- The Ⓟ icon (under the 'Side A/B' indicator on labels) is about a third smaller than the year '1970' to the right of it (until about December 1970 / January 1971);
- Inscriptions (on the right side of the label) 'STEREO', 'SHVL 777' and '(SHVL.777A or B) 33 1/3' are located one above the other and have an equal gap between them.
