Business Blueprints are proprietary for each company. Business secrets are described or inferred in these docs, and they are usually considered confidential. Most of us in these forums have signed confidentiality agreements and could not legally publish them.
Furthermore, BBp's differ with each client and with each implementation. There is no 'right' or 'wrong' format. The right format is the one that is accurate and complete enough to satisfy the client.
If you only wish to see some sample BBp's, try http://www.magnatraining.com/sap/resources/sap-blueprints There are no FICO prints there, but you can get a flavor of this company's idea of what a BBP should look like.
I have found one Business Blueprint which you can download from following link:

It is a protected word document so you will only be able to open as read only.
Hope this will help.
