The phrase "coonskin" or "the coonskin" is on the outside front cover and sometimes on the edge binding of the book. It is not hidden/obscured in any way. I conclude that the "name" of the FHS yearbook is "the coonskin". If you ask for "the coonskin" what you will get is a yearbook. There are likely many copies of the yearbook on bookshelves in homes in the area. I suppose that the Frisco Library has a copy for each year as well, for those who are interested.
The Plano yearbook is "named" the "Planonian" with the 1978 edition page 2 showing "Wildcat" which is their mascot name over the outline of a football player. I have no idea why those names were chosen.
