It’s not a hootie ring. Or a huddee ring. It’s a hudee ring. I still don’t know why it’s called that exactly – presumably there was a Mr. Hudee involved. But now, we at least have a paper trail via these 1958 and 1959 ads. At this point the ubiquitous metal ring for porcelain kitchen and bathroom sinks was sold by the Walter E. Selck and Company of Chicago. And according to the second blue ad, there were 1062 different kitchen and bathrooms sinks to take a metal ring!
In my research, I see there are numerous other manufacturers. But by 1958 some 5 million Hudee rings seem to have demonstrated their superiority in the market. Alas. It does not seem their days of ubiquity would last much longer. Although: You can still get metal rimmed sinks today from Kohler and Crane.
