Creating a Book Poster
The Title and Author's name
Make sure to have a bigger font than the rest of your poster to bring attention to the title and author of the book. This may be the only aspect of the poster they remember.
ISBN, Where to Purchase, Price, Pages and Cover
Be up front with where customers can purchase your book. Including the ISBN number can also help with searching for your book on line. Many times a customer will look for the price and become annoyed at having to search for it and how many pages the book contains. When having your book cover on your poster, you want it to be as clear and sharp as possible.
Be straight forward on what your book is about. Mystery may entice a reader, but clear facts are more likely to progress to a sell if your content is what the customer is looking for.
It's a good idea to show blurbs of your favorable book reviews both customer and editorial.
A photo of yourself - Sometimes customers feel better buying with a face in mind, but this sometimes can backfire.
Contact/Homepage - Your customers may have questions, please keep in mind that this could lead to spam. Directing others to your homepage would be a better option. Treat your e-mail as if it were your phone number.
Don't forget to make sure your poster is printed on good quality paper with rich ink. Good luck!
