Poster Contest Guidelines & Tips

Some guidelines:

You must live or attend school in Petaluma in order to submit.
Multiple entries are allowed.
Collaborative entries are allowed (working as a group is OK, as long as all members are given credit on the entry form).
Be creative and original! We take copyright infringement seriously - don't do it!
Entries must be PG; no mature content. Remember, LumaCon! is a youth event.
While not required, we recommend incorporating something representative of Petaluma into your logo.
Your poster should say "LumaCon!" and the year "2027" as well as the date it will happen, "January 30th from 10am to 4pm / 30 de enero de 10am a las 4pm" as well as the location "Petaluma Community Center / Centro comunitario de Petaluma"
By submitting any entry in this contest, you agree to allow LumaCon! (& all future iterations thereof) unrestricted use of the art, including modification, without compensation.

This contest is limited to participants ages 18 and under.

How long do I have?

Technical Requirements

Your poster should:

have the highest resolution possible (not to exceed 300ppi)
if you are creating a digital poster only, it should be able to print with a height of 36 inches without losing any resolution
if you are hand-drawing your poster, it should fill up an 8 1/2" x 11" page at least
keep color & contrast in mind; we do not recommend blues & reds next to or overlapping each other.

What if I win?

The winning posters will be used on various marketing materials, including the LumaCon website. The winners will receive cash prizes, as well as possible additional prize(s) as determined.

Can I see an Example?

Sure! Here's a really basic example that includes all the required text. You don't have to make your poster look like this-be as creative as you want as long as all the required elements are there.
