Midnight Kiss Collected Edition Cover

In a secret multi-verse where every fantasy character is real – Matt Sable and Nightmare De’Lacy hide a human child from two Supernatural hit men, travelling to Oz and meeting Alligator Kings and Tin Men, while Detective Eindhorn and Jerry Cornelius investigate a dead Angel in LA.

Original pencils by Ryan Stegman.

It's unsigned and not on official art board but a comparison with the published cover clearly shows the pencils match up leaving no doubt this was the piece used for the cover.

There's writing on the back identifying the piece. I don't know who's it is but I doubt it's Ryan's.
