The only BC edition I've got is the Kull one , same pagination , illustrations in B&W though with the paper not pure white they don't look quite as good as in the Del Reys.
IIRC Del Rey only did Coming in HC with colour plates - guess it didn't sell enough to warrant them doing the rest sadly

Thanks. I was beginning to suspect as such, based on some searches here, but was hoping the information was out of date or had missed the relevant threads.

Color printing in the 21st Century isn't as expensive as the 1980s, unless a small print run with high quality inks, but I'm interested in the mass market hardcovers. I prefer cream colored paper to pure white, as the former's color doesn't look as pronounced as the latter's after being aged in a bookcase.
I could pick up the Del Rey
The Coming of Conan with color plates for ~$65, but it'd look out of place with the BC versions and Del Rey or another publisher might re-release the remaining two or all three with color illustrations in the future. I might pick up the Gollancz version, especially for the differences in text and it being an hardback, then wait for proper hardcovers from Del Rey.
Does the BC version of Kull have any of the plates from the Subterranean Press version, albeit b&w, or just plane ink drawings?
