What was on the backside of a dollar bill before 1935?

While speaking with my brother and him telling me that the back of the dollar had reference to the Illuminati, we got to talking about the Great Seal. While looking up what the words meant on the seal I learned it was not put on the dollar until 1935 (I will be looking at a lot of old movies or period pieces to see who was using bills after that time) That got me thinking, what was on the backside of a dollar bill before they put the Great Seal on the back?
