AvPSpectrum is currently running an Aliens competition on their website. Up for grabs is a copy of Aliens Omnibus Volume 1, Aliens #1, a copy of Aliens Infestation for the Nintendo DS as well as a limited edition Lenticular Aliens Infestation Print and a AvPSpectrum cap.
I must admit the print looks quite nice. There are no location restrictions from what I can gather. You must be a member of the site and answer the Aliens-related questions on their competition page. The competition closes December 15th.
