Add Disney Animated Shorts serie

Hello,

I would like to add the mini-series "Disney Animated Shorts" on IMDb, outside the system prevents me because too old (early 1921).

Aside from TheTVDb and the Disney wiki, I have no further information when I want the series back on IMDb.

Could it be for someone to help me do it?
