Its not mis-pressed (The DJ copies are true mono)....It was intentional....they just used the same stamper for both pressings....save a few bucks and charge a buck more for the stereo release anyway....besides the US labels knew mono was gone by mid 1968....
COLLECTORS' NOTE: Epic Records, who had already made a number of pressing errors with The Yardbirds' previous output, really messed up with this album. There are a number of pressings of "Little Games" issued with mono album covers and pressed with mono labels but the album itself is STEREO. To verify if yours is a genuine mono copy, look at the matrix number under either side designation. If it begins with XEM, it is a true mono pressing. If it begins with XSB (despite that the label does not indicate stereo under the EPIC logo and shows the mono catalog number of LN 24313), it's a mispackaged and mispressed stereo copy.
