Vintage Tennis Legends Autographs Ivan Lendl Tom Gullikson Marty Riessen 1982

Description

I found this piece of memorabilia in a frame at a thrift store in Scottsdale, AZ.  The frame was nothing to speak of, so I discarded it.
It appears that it was originally a brochure from The Scottsdale Ranch Tennis Classic, dated September 19, 1982.  It features photos, brief bios, Career Highlights, and autographs from 3 tennis legends:
Ivan Lendl (22 years old)
Tom Gullikson (31 years old)
Marty Riessen (40 years old)
Notice that Lendl's autograph says only "I. Lendl," which seems to be quite rare from the research I did.
The autographs have not been authenticated, but a detailed comparison to other autographs by these men lead me to believe they are authentic.  I accept returns if you determine otherwise.
Measures about 10 3/4 inches across x about 10 1/4 inches tall at the tallest point.
