The latest addition to the décor:

Though the symbolism has evolved into a generic symbol of defiance, the phrase + flag has a cool history. It’s often referred to as a “Gonzales Battle Flag,” but the phrase dates back to (at least) the Revolutionary War:

The American contingent at Fort Morris was led by Colonel John McIntosh… The Americans numbered only 127 Continental soldiers plus a few militiamen and local citizens. The fort itself was crudely constructed and could not have withstood any concerted attack.

The British Col. Fuser demanded Fort Morris’ surrender through a written note to the American rebels. He had 500 men plus artillery. Though clearly outnumbered, Col. McIntosh’s defiant written response to the British demand included the following line: “As to surrendering the fort, receive this laconic reply: COME AND TAKE IT!” The British declined to attack".

In Texas, the symbolism is similar, and dates back to the Texas Revolution, which began with the Battle of Gonzales (really more of a skirmish). The Mexican government had given the town of Gonzales a small cannon to defend against Comanche raids. Due to growing tension between the Mexican authorities and local Texians, the Mexicans sent Lieutenant Francisco de Castañeda to ask the Texians for the cannon back.

As the fog lifted, Castañeda…request[ed] a meeting between the two commanders…. [Colonel John Henry] Moore explained that his followers no longer recognized the centralist government of Santa Anna…

As Moore returned to camp, the Texians raised a homemade white banner with an image of the cannon painted in black in the center, over the words “Come and Take It”.… The Texians then fired their cannon at the Mexican camp. Realizing that he was outnumbered and outgunned, Castañeda led his troops back to San Antonio de Béxar.
