Lesley comments on the Owl perfume mascot out of London; she points out something I didn't know, that owls don't have a strong sense of smell.
As Lesley mentions, the owl as image is a strong and major one in esoterica:
We all know the owl is the most esoteric creature around, associated with alien abduction, bad omens, Bohemian Grove and so much more."They" must know of the owl's powerful impact on the subconscious in this regard. On the surface, one could point to the popularity of the owl in the Harry Potter novels, and the owl in general is a current popular culture motif in fashion. But being of a conspiratorial and Fortean mind, I think this imagery goes deeper than that.
I also agree with Lesley about clowns -- they're creepy and strange and evoke insidious intent -- and mascots, particularly animal ones, aren't any better.
