Sacramento Kings guard Francisco Garcia has signed an endorsement deal with Enlace Spanish Yellow Pages, a division of Cobalt Publishing LLC.
Cobalt is a subsidiary of Blue Equity LLC, a private equity firm based in Louisville.
Garcia, who was a shooting guard for the University of Louisville's basketball team before being drafted to the NBA last year,
will be featured on billboards in the Louisville and Sacramento, Calif., markets and in other Enlace marketing efforts.
Enlace currently publishes 21 directories in Alabama, Arkansas, California, Connecticut, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Missouri, Nevada, North Carolina, Ohio and Tennessee. It also has agreed to buy El Directorio, a Los Angeles Spanish Yellow Pages directory with about 1 million in total annual distribution.
