I have several examples from the Santa Anita Race Book in Las Vegas. Below is a book I found that I almost passed on as I thought I'd had it already. I have never seen another reference to a Santa Anita, Crystal Bay?? I'll assume that this Sport's book was owned and operated by the Las Vegas "strip" location and it's pretty easy to date this book as it mentions Bal Tabarin Club (1955-1960)

Here are example's from the Las Vegas "strip" location c. 1950's, 1960's

And one of my Favorites and rare to find the intact "Feature" matchbook from the noted Santa Anita Turf/Club/Bar (1948-1952) located on Fremont St. This is where the chips that we occasionally see posted here by "Mr. Splash Bar" are from
