Why did the author write this
The most important question to consider when using a primary source is: Who created the source and what was their perspective or bias? Understanding the author's background and intentions will help you evaluate the reliability and relevance of the information provided.
Does the author have any hidden bias
i think that it is a secondary source because it dosen't look like that person who drew it was there
i think they are a primary source.... yes it is a primary source
By definition of a historical primary source (by someone with direct knowledge from the time), a original political cartoon is a primary source. By definition of an English primary source (it is printed), it is a primary source. By definition of the final form of primary sources (see definition of primary source on www.answer.com), it is based on someone's interpretation of the time and is thus a secondary source.
In my personal opinion, it would be a second source,
Primary source because a primary source is from the past/something from someone whose been in that time but a secondary source is something from us/people who have not been in that time, and its also what we think happened then.
A primary source would be a picture from that time. Or something like a diary. I think Davey Crockett had a diary of what happened.

Primary sources (in history) are things such as documents produced at the time. A secondary source is something written later by a historian. Good examples of primary source documents are legal notices, letters, diaries, newspapers, maps, flags, important documents, clothes, and even furniture.
I don't think I understand what you mean by the "primary source". If you are referring to the primary source of information on PPXII, the answer is Sr. Margherita Marchione. She is the ultimate expert on PPXII as acknowledged by the Vatican. Check out her web site. She has written many books on PPXII. www.Sr. Margherita Marchione.com
