Oil and Gas Certificate

I recently discovered an old certificated in my wife’s belongings issued by the Van Zandt Oil and Gas Association of Edgewood, Texas. It was issued to W.B. Cheatham on November 6th 1919.for two interests in the said Association. Would anyone have any information about this?

Welcome to the forum. Have you tried an online search? Given how old it is, probably no longer in effect.
