El Diablo, Elric, Pat Boone, Golden Age Sandman, The Shadow

Anyone remember the best version of El Diablo?
The Helix imprint gave DC an opportunity to experiment with Elric.
Remember when real life characters showed up in DC and even interacted with characters like Superman?
I hope this Sandman makes a return with the Earth Two series.
When DC had the Shadow, they did a pretty good job.
