Some classic rock albums have cover art so trippy, it could be pulp science-fiction book covers. (Like that Queen one.) Can you tell the difference between album covers and pulp book covers? Take our quiz!

And before anyone else says it, yes there a few well-known covers sprinkled in here. Because I couldn't resist. I'll post what all these covers are either tomorrow or Wednesday.

Thanks to Irene Gallo for the idea!
