hi Yoc,
great to see Colossus.
i was so intrigued by the unusual style of Bernie Wiest on that story (comics.org credits different artists on the Lum Sims and the Tulpa stories but i would not be surprised if Wiest had a hand in those as well?) that i duckduckgo'd the man.
found a blogpost obituary for Bernie's wife Sim from 2009 and have emailed the poster, a grandson, for more info.
i'll let you know what i hear.

two hours later...
p.s. already heard back from Bernie's grandson, who is putting me in touch with his daughter. expect to learn more, hopefully sooner rather than later.
