I ordered this map from Amazon (rather than from one of their 3 currently listed alternative suppliers) and the map I received has printed on it 'Edition 8 - 2010'. This clarifies something which puzzled me when ordering, that Amazon's product info indicates it's from 2003, so apparently somewhat out-of-date. Amazon gives the same ISBN numbers as given on the barcode of the map I received. Perhaps it's a quirk of Michelin's ISBN numbering meaning that Edition 1 (2003) to Edition 8 (2010), and presumably beyond, retain the same 2 (10-digit & 13-digit) ISBN numbers.
The other thing I'd been curious about was the size of the map since it doesn't seem to be mentioned either by Amazon or by the customer reviews at present. The bar code sleeve on the map I received claims it to be '0,88 m x 1,00 m' - which equates to around 35" x 39" (or 2'11" x 3'3") for imperialists!
I can't comment convincingly on the map itself since I don't want to unwrap it, given that it's a present for someone else. Nevertheless, the slice of Ireland I can see without unwrapping looks impressive!
