Graduation Picture of Grandma

Thanks to info provided by my Cousin's wife, I am able to share a great photo of my grandmother. This is the type of thing that is great about the Internet. Before the sharing of so much information, I would never have come across this piece of my history. She graduated with the class of 1935 at Texhoma High in Texhoma Oklahoma. Is it me or do they all look like they are already 35 years old??
