John Copeland was a US-based photographer for Penthouse since 1977. He was based in Germany from c.1981-88, working for both Penthouse (De) and Playboy (De) before shifting back to the US (California).
He owned the pixotna company/brand & website.
He now is linked to
this website & studio in Las Vegas.
Here's his bio. page, including some slightly different (probably more accurate?) dates for all the moves.
Some known AKAs:
Jo[h]n Harro[l]l -- i.e. Australian Penthouse sometimes left out the H &/or one of the Ls.
John Midi
Patsy Smile
Jack Callis -- in Hustler Rejects 08, 1984
Oddly, although AUPH mostly used the John Harroll name they included a feature about him under the name John Copeland in 1994-10
here in which they acknowledged the varied names... but did not explain the reason for them.
