There is quite a few differences between the lettered and limited edition of Carmilla. It has a different leather binding, black instead of red (I actually prefer the read a bit), sprayed silver edges, different endpapers, an additional colour art piece and a small Remarque from Alex McVey.
I actually prefer these to the limited edition, but both are really eye catching.
Love the V V for this lettered edition.
The art beside the Remarque is the new piece, possibly the best in the book.
