Poorly printed Pokemon Red/Blue manual - genuine?
I posted this on the gameverifying sub a few days ago but didn't get any responses there, so hope it's alright to crosspost here in case anyone can help. Sorry if this thread falls foul of rule 6 (I couldn't actually find the fake cartridge thread mentioned in the sidebar).
I bought a loose manual for Pokemon Red/Blue to complete my box and cart only copy of Red. I've noticed that it has a printing error on several pages where the printing is somewhat misaligned, if that's the correct term. I can't see anything else wrong with the manual, so I'm wondering if this is likely to be a genuine printing error, in which case I'm fine with it, or if it's a sign that it's fake?
More generally, is there anything I should be looking at to try and tell a fake manual from a genuine one?
