Well, you're not alone. This is the number one request I receive on yearbooks.com.
The problem is to find an old yearbook is very difficult. When schools places there order for year books they only order for the number of student that have ordered.
Possible they may order a small number on speculation. These books generally sell out and often students wishing to buy a book that year are out of luck.
The only place I can send you is back to your school. The library may have a copy.
I don't have a copy nor can I help you passed this statement
