"Secret Garden" Cover - http://www.barnesandnoble.com/p/lilly-pulitzer-secret-garden-cover/19915875
Try eBay. I got the Secret Garden one for the original Nook on eBay...my orginal Nook has a Sparta 449 cover...what I wanted this one for was my 7" ViewSonic Viewpad tablet and it fits perfectly!
Happy Hunting...you might save an eBay search for it so they email you whenever they find any...that way you won't miss out on one if it becomes available.
Edited for spelling. Used the PC for a week now I can no longer type on the Mac! *sigh*
Please tell me that you're looking for the old Lilly Pulitzer covers for a Nook 1st generation model and not the newer Nook Simple Touch model. The devices are different sizes so the covers for the 1st generation Nook will not fit the Nook Simple Touch
I have the LP Secret Garden cover (for Nook 1G).
