EFO Students: What can you say about these? They were featured in the October-December 2013 issue of The EFO Collector!

We collect stamps and postal stationery items that are different than intended... They may
be misprinted, miscut, or otherwise mishandled during the production process and are therefore
special. Here are a few examples:
Stamps and postal stationery items that have production errors are called Errors, Freaks
or Oddities, depending on the type of the error. A particular error is usually relatively rare, but
there are many of them.
Watch this video that explains why collecting EFOs is a lot of fun!
Our Club provides members with information regarding Errors, Freaks and Oddities and
is therefore called Errors, Freaks & Oddities Collectors' Club (EFOCC).
The EFOCC provides rich membership benefits, such as:
Subscription to The EFO Collector, our award-winning quarterly publication,
A quarterly auction that allows members to sell and acquire EFOs,
