Michael Larsen writes in his book, How to Write a Book Proposal, that writers should include an 8x10 black and white photo of themselves in the jacket pocket of the proposal. I had a professional photo taken of myself for this purpose and found that the 8x10 is rather, "Here I am, look at me!" but a 5x7 turned out nice, and is more humble and professional looking. However, I am interested to know the opinion of others on the matter. I think that the photo helps an agent to know that I am 'marketable' in appearance. But does anyone think the photo is is a bad idea in general or, if not, why Larsen would suggest it? He did not say why in his book.
