Here’s a potential cover for a non-fiction history book on Lovecraft and astronomy. I’ve taken off the pre-existing text (it was the cover for an old booklet from India), fixed an obscuring label, and also re-coloured. It’s 2,900px on the longest size and thus should work for a cover / back-cover on a Lulu.com 6″ x 9″ book.
The space on the right could potentially host a Fivver-commissioned cameo done in the same style, featuring Lovecraft’s face. Or perhaps the Lovecraft silhouette in cameo, with a holding line added around it.
