High Summer's darkness descends on Moonbase like suspicion
I see the sinister in smiles
Like the exposed gums of Millennium's Cthulhu cover
They recall the mad maw of King Crimson's Crimson King
and the crazed vast smile of Famous Monster's Sardonicus
Hands can be menacing too
Consider John Russo's Return of the Living Dead paperback cover
where blue hands bring terror
as they do on the cover of Eerie 10.
Do you know of any similar horror covers.
