26 color plates. The Vault of Horror #15-40. Missing the first three covers: Vault of Horror #12-14.
These prints are the same covers used in the COMPLETE VAULT OF HORROR, as such, they are on the same glossy stock and the inside front cover is printed on the backside, however these are trimmed to include a white border and the entire cover.
From the publisher:
The ... covers contained in this envelope represent some of the finest artwork done for EC comics. These are the same covers used in the COMPLETE VAULT OF HORROR, except that they are trimmed to include the entire cover. The artwork, mostly by editor Al Feldstein, was colored especially for this series by the original EC color artist, Miss Marie Severin.
