John Kenneth Lamb (7/7/1911 – 11/28/2006) was born in Oshkosh, Wisconsin to John Otis Lamb and Nelle Evangeline Martin.

Lt. Colonel John K. Lamb volunteered for duty in the Army Air Corps the day after the attack on Pearl Harbor, WWII. He served in the Classified Message Center as Top Secret Control Officer, Chief of Organization and Planning, Central Pacific Headquarters, Guam.

After the war ended, Lamb founded Cincinnati Sign Supplies in Cincinnati, Ohio in 1946 to meet the demands of the rapidly growing market for sign and screen process supplies and materials. In 1950, Lamb added Texas to his growing business when he founded Texas Sign Supply. He asked a local accountant, Roy Baxley, to take on the company as a client, and also to serve as Treasurer. Roy accepted, and in 1954 sold his accounting practice to become the full-time President of Texas Sign Supply Company.

One of their first employees was Hank Granberry, who started as a warehouse clerk, who would eventually become the President and owner of the company.

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 who started with the company in 1950 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 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 continuing as Chairman of the Board.

In 2006, Mark Granberry purchased the company from Roy Baxley and became sole owner of the Graphic Solutions Group, which evenually became GSG.

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.

In 2016, GSG acquired John Lamb’s original Cincinnati Sign Supplies, expanding the company to serve Tennessee, Indiana, and Michigan.

John Kenneth Lamb passed away on November 28, 2007 at the age of 95. He was survived by his spouse, Susan I. Webster-Millikin, stepson Michael Douglas Millikin, daughter-in-law Marilyn F. Lamb. He was preceded in death by his son David John Lamb.

Mr. Lamb was a member of the Society of the Cincinnati, Colonial Wars Society, Military Order of World Wars, First Families of Virginia, Queen City Club and Clan Lamont (Scotland).
