Dallas Oil Company of Texas stock certificate 1960

Awesome modern petroleum stock certificate with colorful oil field vignette. Interesting yellow seal number blocks. Issued and cancelled. Dated 1960. Heavy folds as shown but no tears or other damage to the cert.

Incorporated 1954 in Dallas Texas. Recapitalized in 1982 as the Dallas Oil Company and bankrupt in 1984 with tax payment problems.  Maybe an inspiration for the tv show Dallas and the Ewing family but still a fun piece and remarkable design.
