Seeking history of the Texas Brand Boot Company.
I have a pair of vintage ladies cowboy boots, and I'm trying to guesstimate how old they are. They could also possibly be girls boots, because they are a size 5, which is usually a size you find both in kids and women's shoes. The company that made them, Texas Brand Boots (which was actually based in Tennessee), seems to be defunct as of the past few years. Apparently, their niche was affordable American-made boots. The oldest mention I can find of them are late '70s print ads on eBay.
My boots seem older than late '70s due to the style, construction, and materials, even compared to the ones in the ads and on eBay. I have no way of confirming this, however, without more info on whether the company even existed before that. I don't care if they're not older, since I bought them for their looks, not their age, but I'm just curious.
Does anyone know where I can find more info on this company's history? Or know that they were around before 1978?
