I was curious, since FSM is hangin' the "Master" tag on folks in every issue it seems... What made me notice was the recent article of Doog's where he was reffered to as "Master Modeler Karl Logan" in the Hetzer build. Make no mistake, I'm not saying that Doog doesn't deserve the accolades he gets, in fact, it's quite the opposite... (I know it's been said many times, but Doog, you ARE among some of the best modelers I've seen in my 40 years of doin' this stuff...)
Regarding being published as criteria, I wondered about that, since there was one modeler who was a regular contributor to Scale Modeler and Military Modeler magazines back the 80's/90's, a guy named Duane J. Phister who primarily built dioramas. His builds, towards the end, were featured in about every issue of those mags, always for sale (said so in the articles), and he even had his cartoons published in the mag (Modeltoons)... But, I never really saw anything that jumped out at me as being "superior" about his work, although it was always good, really good stuff, with many diverse subjects... I recall one of builds was a scratchbuilt diorama of "IPMS Night" where he used the 1/24 scale figures from Tamiya's Pit Crew and various smaller-scale figures, planes, tanks, ships, etc and scratch-built tables and chairs to "model a group of modelers modeling models of models"... It was one of the most original ideas I ever saw, lol... His work was always immediately recognizable as well, I never had to check the name of the author on the articles when they ran, you could tell it was Phister's work right away (Usually by the ever-present tarps, which appeared in almost EVERY build)...
At any rate, this is turning out to be an informative little topic, if I do say so m'self... Although I don't compete, I have judged in the past and it's always amazing to see the work that folks put glue to...
It's forums like this one as well, with people like y'all that are willing to share your work, give tips and tricks, and instill confidence in other modelers who may have given up in the days before the internet allowed them to easily see other's work and to actually ASK the guy "How'd you DO that?"... To me, y'all are "Master Modelers"... I myself will never get to the level of Hizzoner, St. Shepard of Monogram (Cue angelic fanfare music), or the vast majority of y'all, but I'm gonna die tryin'...
