Any way to see ranked history?

So this season has been pretty good too me and I've climbed up the ranks successfully (at least it feels that way). I think I started out in Bronze V but want to make sure before I make a guide for low elo Zilean play. Is there any way to see where I started last season? Trying to get to gold before the new provos reset solo/duo to prove my build/strat/mentality works!
