I would not recommend doing that.
It's just a typo. The only time it would ever come up is "Oh, I see you did a poster in 2011?" in an interview. In which you would reply "Oh, sorry, 2010." and then move on to describe the poster. Or make a time traveling joke. Pretty much anything.
Don't shine a light on it in your secondary. It's going to be either ignored, really jarring if it's written weirdly, or just waste their time. Changes are they're just going to skim right past it when they're reading the typo.
