On Isabel Bloom statues, what does the circle and the letters in the circle mean?

I know the artist initials their work, but what about, for an example, an r with a circle around it, or a c with a circle around it. I don't know what that means. Also, if you can elaborate on what usually is written underneath an Isabel Bloom product, that would be great. Thanks!On Isabel Bloom statues, what does the circle and the letters in the circle mean?
I don't know if they will show up here but 漏 庐 are the international symbols for Copyright and Registered Trademark. Just today we were visiting the Amon Carter Museum in Ft. Worth and a Remington bronze of a bucking horse and rider had the copyright notice molded in the bronze base. Prior to about 1977, the only way in the USA to secure the copying right was to put the notice in proper form on every instance of the protected art. Proper form was the word Copyright or C in a circle, the date, and the name of the copyright holder. And it had to be registered with the Copyright Office and be renewed. At that date, US law was changed to match most other countries - automatic copyright upon creation of the work and maintained for 50 years after the creator's death without registration.


R in a circle declares that the image, word pattern or shape is registered as trademark with a government office. For instance, at the top of this page Yahoo! is shown with a 庐 That means that the red letters of that shape with an exclamation point are protected and nobody else can market say a soda with that image on it the can. Whether it also means that the 6 typed characters Yahoo! are trademarked is another matter. On a statue, it means that she has registered the exact shape of her initials, probably.
