I have an original OEM Jaguar fold-out brochure for the XK 150 models (convertible and coupe), wherein they boast about the "new" Dunlop disc brakes!  The brochure is 8 1/4 x 12 1/2 inches, and opens up to 16 1/2 x 25 inches.  This particular brochure is in excellent condition with no discoloration or smudges, one corner (top right) has very slight bend.  Refer to the multiple photos provided to verify condition.  Note that this is not the same one that I sold earlier (March 4), and I have provided new photos of the cover of this second brochure.  Appears to have a May 1957 printing date.  Free shipping on this item to the lower 48 states.  Sorry, but no international shipping is offered by me directly.  Use the eBay Global Shipping Program for that service:  https://www.ebay.com/help/selling/shipping-items/setting-shipping-options/global-shipping-program?id=4646
