This section provides details on the elusive Errors, Freaks and Oddities (EFOs) of the Scouting topical area.  The foundation for this section is from the article series "Errors and Major Varieties in Scout Philately" by Sheldon S. Levy.  Further reading is suggested in the 1998 Catalogue of Errors on US Postage Stamps by Stephen R. Datz.
