What canon Snape should look like

[Heather]

I've noticed people saying what they think Snape should look like in 
their mind versus Rickman's Snape and the drawings of Snape in the 
various books. Have you all seen this? It's a drawing done by JKR 
herself of how she envisions Snape. This was on that special from 
several years ago on the Biography channel, I believe. Harry Potter 
and Me, I think it was called. It's been repeated several times since 
the original airing. I guess it was on A&E in their Biography channel 
segment. Anyway, I am babbling. This should clear up what canon Snape 
should look like. We can still all have our own visions of him. This 
is just the author's vision of him.
