Is it just for local customers?

Not that I'm aware of. Deadline for entry is Feb. 17th, though, so if you can get them printed and mailed in time, you should be fine. However (presumably because they're not accepting submissions electronically), I can't find an online version of the entry form. The only mention of the contest I can find online is here. If you really want to enter, you could give them a call at the Beverly Hills office (which is where the photos are supposed to be sent to), and have them fax you an entry form.

If you want more details, let me know.
