Penny Black 175th Anniversary Country Issue List

Hello,

I am interested in compiling a thematic collection relating to last year's one-hundred-and-seventy-fifth anniversary of the Penny Black and eighteen forty two pence blue.

I would like for this to include, wherever possible, stamps from all of the countries that celebrated this anniversary with postage stamps in twenty fifteen, including those, like Sri Lanka, for example, those that used this anniversary for a different purpose, for example World Post Day; Sri Lanka used the anniversary as the theme for the stamp for such a purpose.

However, I haven't been able to find any complete list of all the countries that issued Penny Black anniversary philatelic material last year, meaning I can never know whether the list of those countries I do have some anniversary stamps/miniature sheets/first day covers/etc. from is a complete one.

I would highly appreciate the help of anyone who has such a list that I am looking for.

Thank you,

James

James, as is the case with all Omnibus issues, you can always contact the ATA, the American Topical Association. They issue lists of these things.
