1) Go To Ebay.com and do a search for yearbooks.
You'll find large numbers for sale.
2) Contact your School directly and ask them if they have copies available for sale.
Here is the link we have to the School website:
San Marino High School
3) See if any of your friends from school has an extra copy they would be willing
to let you have. You can use the Discussions page
to solicit help from others.
