Here's something I found by exploring the archives, a television advertisement for the Australian Labour party. I think it was for an election that was held in 1966, LAST CENTURY!!

Wow!! what an interesting Ad!! What has changed and what is the same?? I wonder if Goff Whitlam won that election??
What issues were most important to that Political party then??
What issues are considered important now??


This is a fantastic site that is the website  of Australian  Screen archives, old TV Ads, television documentaries etc. These are completely acceptable sources of information for your Project. Again, think about your presentation, and an interesting way of incorporating interesting resources.
