The name "Art Portfolio" here is slightly misleading, as it does tend to bring to mind individual glossy art prints in a special envelope. Instead, these were magazines, in the same format as The Heroine Addict/Showcase and The Adventuress, the CHFC's fiction title - they featured just full-page artwork by the team, other than the contents page. The first Portfolio had a wrap-around cover by Mercy van Vlack, and pages inside by her as well, plus Ted Delorme, Kirk Hastings, Phil Laskowski, Tom Luth, Tom O'Reilly, Chris Padovano, Bob Rodi, Wes Smith, Carol Strickland, Scott Taylor, and Frank Travellin Jr. All their pictures can be found in the pdf file here; as well as the cover, I've put small reproductions of pages by Frank Travellin Jr (page 7) and Carol "Strick" Strickland (page 8) on this page just to whet your appetite!
Hopefully we will eventually get the artwork for the later issues to post here as well, as at the moment this is a rather short page...
