Where to find some very old stock price

[Lexus007]

Hello guys, I am doing a research about the Great Depression. I need the stock prices at that time, for example General Motors stock price during 1929-1935. I tried but could not find in any stock quote website.

Does anyone know where to get this ? Thanks
