People in Libraries on Postage Stamps

I'm a collector of libraries and librarians on postage stamps which is sometimes called bibliophilately. Of the hundreds of thousands of postage stamps that have been issued by the countries of the world, less than a thousand fall into this category. Of that group only 30 to 40 depict people inside of a library (this does not include images of celebrities in a library). I'm an advocate for a United States postage stamp or group of postage stamps honoring public libraries. Stamps showing people using public libraries would be a great way to do this. Below are some of the stamps in my collection showing people in libraries.
