Stock certificate #1 issued to Adelaida Cuellar, dated May 16, 1962. The certificate is matted but not framed. The certificate states the following: "This certifies that Adelaida Cuellar is the owner of Six Hundred fully paid and non-assessable shares of common stock, without par value, of El Chico Corporation a corporation organized under the laws of the State of Texas, transferable only on the books of the Corporation by the holder hereof in person or by duly authorized Attorney, upon surrender of this Certificate properly endorsed."

The Cuellars were among the early entrepreneurs who helped transform Tex-Mex food into the most popular and widespread form of Mexican American cuisine. Adelaida Cuellar was the original operator and owner of Cuellar's Cafe. The cafe would later become the popular Tex-Mex restaurant El Chico, once transformed by her sons in the 1940s.
