I participate in several Libertarian discussion groups. On one, I asked for references to businesses that make campaign materials, preferably those owned by Libertarians. I was directed to a business card company and a bumper sticker company.
Yesterday I called the bumper sticker company, and discussed what I wanted for the campaign. We discussed sizes of the bumper stickers, colors, and wording. I left a lot of the decisions up to them, as I am not a designer (the extra cost for them to produce the design was relatively minimal, on the large scale). So now, hopefully within the next few hours, I should be getting rough drafts of various designs for bumper stickers.
Just as an FYI: I WILL be making the bumper stickers available (autographed, if anyone actually WANTS my autograph) through my blog. Because there are goods being exchanged, it doesn't count as a campaign contribution as far as the Ethics Commission is concerned. So anyone who wants to purchase them, can. It will probably be about a month before I get them, though; I'll keep y'all updated.
