I have this Procol Harum album with autographs superimposed on the album cover in blue. The Wikipedia cover picture does not show the autographs and my Goldmine doesn't mention it.
Anyone have any info on this? I'm kinda curious about why my cover has these.

My copy has "writing" on the front and back. Front: group autographs. Back: "During recording our ninth album - April 1975" by photo.

Yeah some of the covers (even on cds) had this.
