I used to have this back in the day but have lost it since, it was this windows desktop background but edited to have the titular hammer from Lucifer and the Biscuit Hammer in the sky. I drew a shitty version here but its much bigger with less of the handle showing, and more subtle/shadowy like the reference images I have from the manga in the same album:
