So for my speech class, we're supposed to give a 7-10 minute informative speech. We are allowed to do a "History of" type of speech so I thought, Hey! why not do a speech on Transformers! Right now, the only roadblock that I'm facing is that we need five sources, two of which have to be a non-internet source. I'm looking to get a copy of the Transformers Vault book, but I still need at least one more. If someone could point me in the right direction, that would be great!
