I don't know how it would go over if you put this promotional material and business cards on the contest tables next to your models....However, most shows allow people who are so inclined to purchase vendor tables that they can set up with material they are looking to sell, or advertise. I think you would probably benefit from that angle. Then you could set up a display of your dioramas and other promotional items from your magazine, separate from what you enter into the contest. That's just my thoughts...
I tend to agree... A vendor table would be the most ethical route... Personally, I get turned off by being "slipped" advertising under the guise of something else... But there's a fine line(and a blurry one at that) between genuine information and shameless advertising/self-promotion, and it's easily crossed... Trouble is, you won't know when you'll crossed it, as it's not defined by you but others, and each line is as different as the individual... For instance, I get turned-off by advertisments in member signatures around here... I got no issues with the same thing in the advertisment SECTION of the magazine or website.. But in the forum member's sig, well.. That's unethical, IMHO... It strikes me as an attempt at circumvention of the FSM site's advertising policy...
As they said at the start of "The Atlanta Course" (a required 12-hour course at the US Army Recruiter School that's taught by a civilian rather than a Army Recruiter Instructor, believe it or don't), "People hate to be sold anything, but they love to buy!"...
Remember the Decoder Ring and "Annie's Secret Message" in the movie, "A Christmas Story" and how PO'd that Ralphie got after decoding the "Secret Message" that read, "Be sure to drink your Ovaltine" ? A lousy commercial! He never mentioned Little Orphan Annie OR Ovaltine ever again! So the ethical route, IMHO, would be a table, a few cards, a diorama or three, and a flyer or pamphlet, similar to what Shep Paine did for Monogram, containing the how to, & what with of your dioramas, and where the inspiration comes from, including how to get it...
