I've removed my ramblings ok so what I was trying to say was if you apply error correction filter in GIMP on different pages on LP and scan the image with QR code reader on your phone you will come across sets of numbers, after lots of trial and error and loads of sets of codes (typically UPC A and EAN 13) what you will find is loads of these serial numbers I've googled the ones that I came across and 99 times out of 100 it's just a re used product id for a barcode (I kept on getting the same results over and over; waste pipes and parcel tracking numbers. This was pretty amusing trying to figure out what it all meant but I know nothing of coding and cyphers etc so I didnt even know what I was looking for. Eventually some of the pages would say "aztec text" and contain different letters. I'm not entirely sure what they are I think they are ancient greek, there is the german letter that looks like the letter B but is pronounced SS (apologies for lack of image I'm using my UK keyboard on phone, and the other was the letter a with the 2 dots above it, also if you keep digging eventually you will come across the original text. The bits that have been decrypted might have been in runeglish but I would imagine at least a large portion of the rest will be in Latin.
