Below is a picture of a REAL original Mono Piper.
1. The fake doesn’t have this cardboard ‘over fold’ where the ends of the front cover are folded over to the back.
2. The fake bears the catalogue number of CX6157 whereas the original is numbered SX6157.
3. The copyright warning in the bottom right hand corner is missing on the fake.
4. Perhaps most telling of all. The original had a laminated front cover, with a semi stiff cardboard back cover. The fake is laminated back and front.
