I have an Oberon for the original Nook WiFi model, which I believe is the same dimensions as the original Nook 3G/WiFi model.
My cover was used for less than a year and taken good care of. I gave the Nook to a nephew, but I thought the cover was probably not his cuppa, he got hubby's black leather BN cover instead.
It is the Van Gogh Sky design in sky blue. Condition is very good, I don't currently have pictures, but I could certainly take some.
PM me your location/zip code, I'll give you a quote that includes shipping.
