Henry Lee “Hank” Granberry (Jan 31, 1925 – Aug 11, 2001) was born in the small East Texas town of Hawkins. In 1948, he married Mena Gene Wilbourn, a fellow East Texan from Wills Point, while he was serving in the U.S. Navy. They had four children, Michael Granberry (Nancy Churnin), Mark Granberry (Charla Granberry), Mallary Henrichs (John Henrichs), and Larry Granberry (Jill Granberry).

When Hank left the U.S. Navy in 1950, he and Mena settled in Dallas, Texas and Hank accepted a job as a warehouse clerk at Texas Sign Supply. The company was just beginning, having been founded by John Kenneth Lamb, the founder of Cinncinati Sign Supplies of Cinncinati, Ohio, and Roy Baxley in 1946. Hank quickly worked his way up in the company and received many promotions.

The Texas market quickly expanded and Texas Sign Supply moved into larger headquarters on North Walton Street in the Deep Ellum section of Dallas where they continued to grow. In 1962, the company also expanded northwards with the founding of Neo Sign Supply in Oklahoma City to better serve their customers in Oklahoma, Arkansas, Kansas, and Missouri.

The screenprinting market was advancing rapidly and in 1966, they purchased another building across the street at 310 North Walton Street and opened Texas Screen Process Supply Company, Hank Granberry was promoted to President of Texas Screen Process Supply and Baxley as Vice-President of Texas Screen Process Supply, and  President of Neo Sign Supply. Eventually, the two companies would expand the 310 North Walton Street location in Dallas and combine the two companies in the same building. Roy served as Chairman of the Board for all three sister-companies. Eventually, Roy Baxley and Hank Granberry would purchase the company from John Lamb.

In 2001, the three companies were merged into a single company with Hank Granberry’s son, Mark Granberry, who like his father had started working as a warehouse clerk at Texas Screen Process Supply as a young man, took the reins of the company. Mark merged all three companies – Texas Sign Supply, Texas Screen Process Supply, and Neo Sign & Screen Supply — into a single company – Graphic Solutions Group with Roy Baxley continuing as Chairman of the Board.

Five years later, in 2006, Mark Granberry purchased the company from Roy Baxley and became sole owner of Graphic Solutions Group, which eventually became GSG. In 2016, GSG acquired John Lamb’s original Cincinnati Sign Supplies. Today, they have nine locations in Austin TX, Baton Rouge LA, Cincinnati OH, Dallas TX, Denver CO, Houston TX, Milwaukee WI, Minneapolis MN, and Tulsa OK.

Today, GSG is a leading national supplier to the sign, digital imaging, and screen printing industries. The company has moved to larger headquarters at 4601 Spring Valley Rd., Dallas, Texas.

Hank Granberry passed away from pancreatic cancer on Aug 11, 2001.
