Here it is: Texas, Model 1836. The original. Accept no substitutes.
On December 19, 1836, the Congress of the Republic declared that shape to the world:
"Beginning at the mouth of the Sabine river, and running west along the Gulf of Mexico three leagues from land, to the mouth of the Rio Grande, thence up the principal stream of said river to its source, thence due north to the forty-second degree of north latitude, thence along the boundary line as defined in the treaty between the United States and Spain, to the beginning."
Texas. Model 1836. Iconic.
