As you used the term "advertising", I figured I should highlight the following from the web page.
NOTE: Norwescon reserves the right to reject any material deemed unsuitable or inappropriate (this has very rarely been an issue in the past). Any materials placed in the registration packets must be appropriate and suitable for a mixed audience of SF fen, including those under 18. Norwescon does not sort the packets by age of recipient or any other demographic criteria.
Non-SF&F related commercial or political materials may not be accepted. If you are at all concerned about your material, please submit a sample to the Con Chair for review in advance. Any materials not reviewed in advance will be reviewed by the Con Chair at the stuffing party and may be rejected at that time.
If you have concerns about if a flyer will be acceptable, please send me a PDF in advance so I can review it.
