This is the worst argument I have ever seen. Of COURSE you would you've seen him in movies and on TV. This is a time with nothing other than couriers for spreading info to the masses. No pictures, no film, we don't even know if they had a basic printing press.
I do agree it was strange when they recognized you for a specific skill. I thought it strange that someone would walk up to me and say "You're a sneaky looking sort." Just cause I was a Redguard. Racist mother****ers...
Are you even being serious right now? Have you even played Oblivion? Done the Thieves guild? Have you even walked in the Imperial City? There are posters everywhere.
Also, you don't have to see someone on TV to know who they are via description. Word of mouth goes a long way. And yes, people made posters and pictures of people.
Seriously, I can't even tell if you're being serious or not with how you replied to what I said, it was that ludicrous.
