My memory is hazy, but was there a seller selling these and NOES quads on ebay and they had more than 10 of each?
The NOES had an easy tell (the cropping on Freddie's hat), but I don't think the photos of SW were good enough for an easy tell. Hopefully the paper would make it obvious, but that photo does make it look quite 'realistic'. Buyer beware on these I think.
