Vintage Advertising Pen and Mechanical Pencil Lot

Got a small lot of vintage advertising pens and mechanical pencils here. Includes a cool Dallas Cowboys pen, a Holt Machinery Co. one, and a few others from Texas companies. They've definitely been used and have some wear from age, but they're great for a collector or someone who likes that old school office vibe. Not sure if they all still have ink or lead in them, selling as-is.
