Errors, Freaks & Oddities on U. S. Stamps

Question Marks in Philately

Dr. Stanley B. Segal

The EFOCC is pleased to present the philatelic community a reprint of Dr. Stanley Segal's work, Errors, Freaks & Oddities on U. S. Stamps. When it was published in 1979, it was a ground-breaking achievement, one of the first works focusing on EFOs, and helped place EFO collecting into the mainstream of philately. You can read this book in one of two ways.
  1. You can view the pages online by clicking on the items in the table of contents shown below to see the related pages. Once you are on a content page, you can move from one page to another by clicking with your mouse on the arrows under the pages.
  2. You can also download the complete book onto your computer by clicking on the link below. If you do that you need also the PDF Viewer from Adobe software (likely already installed on your computer). Also note that the file is fairly large, and it might take a while to download to your computer, in particular if you are using a slow (dial-up) connection.
