Given his mention of knowing Steranko and Eisner, it appears to be the same Richard Rae. Richard organised one of the first comic cons in Australia in the mid-'80s (or thereabouts) and the guests were Steranko and Eisner.
I've never met Richard in person but I corresponded with him a number of times a couple of years back. It wasn't until about a year (?) ago when the issue of selling lightboxed Kirby pieces inked by Mike Royer as all original Kirby/Royer came up and I was disappointed to learn that he'd knowingly sold them as such
Of course, then followed the Vince Greck/Estate Clearing saga at the CGC OA forum where Vince claimed to be selling artwork from Richard's deceased estate (after people pointed out that some of the pieces Greck was offering had previously been offered by Rae). Only thing was that a check of the ABN register didn't turn up any business by the name Estate Clearing and Vince Greck was believed to have been Richard Rae under a pseudonym.
One of the pieces offered by Greck was a lightboxed Steranko/Buckler piece which was offered as all original Steranko/Buckler. However, the original pencils belong to Jim Warden and can be seen in his CAF gallery. Also, I contacted people who know Richard Rae and they assured me he was still alive and that his twitter account was still in use. Plus Mike Burkey said he'd been in recent (at the time) contact with Rae. (Richard's now popped up here and I'm guessing it's the same person).
Greck was later removed/banned from CAF for fraudulent behaviour and for taking an image from another CAF member's gallery (Terry Doyle) and offering it for sale.
Lately, a new member has turned up at the CGC OA forum known as Captain Australia who has some sort of conspiracy theory about abuse and bullying behaviour by CAF hierarchy - presumably as regards the action taken against Vince Greck.
I would not be surprised to learn that Captain Australia is identical with Rae/Greck as the poor grammar, misspellings and syntax are all consistent between the 3 identities. That's just my take on the situation.
