Belding Bros. & Co's Spool Silk Advertisement.
These types of vintage advertisements appeal to me a great deal. Possibly it's because I know the product, but advertising in those days was a form of art. I wish that today's advertising was more like it was back then, instead of being full of sexual innuendos and stupid men that pretend they are cats. I tend to avoid products that use that type of advertising. What about you? ~Blessing, Mary~
