The text of the postcard is
This postcard represents Christmas shopping with absolute accuracy.
Yeti with battle axe = you, the shopper.
Ominous red sky with doom-threatening lightning = traffic around the mall.
Dangerous and possibly deadly castle in the distance = the mall.
Unicorn casting judgement from above = jerk about to steal the parking spot that should be yours.
Good luck out there!
