I'm not sure this belongs with graphic novels and such, but... In answer to your question, there are tons of anthologies which have collected together stories from the pulps, including several devoted either exclusively to Weird Tales, or to "The Unique Magazine" and its competitors (Strange Tales, Tales of Magic and Mystery, etc.) I've got several, if this is what you're asking about.
On the other hand, if you're looking for facsimile reprints of the original pulps, I don't think there have actually been any of those, as the copyrights would be a real tangle; but a few might have been done over the years. You might look into the things offered by Wildside Press, as they've revived some of the old pulp titles in their catalogue, and may have some facsimiles they've done.
If the anthologies mentioned above are what you're looking for, let me know, and I'll give you a list of titles to look for; many of them show up in second-hand shops quite frequently.
