I began to collect stamps in 2005, I collect "only" stamps on which are depicted CW morse keys, the choice is not so huge, and you have to search every day (fortunately bots are very useful !)

Four main companies are working hard to deliver us catalogs of all the stamps that can be found on Earth, the first one is Yvert & Tellier and is based in France, the second one is Scott, the third is Michel and the last one is Stanley Gibbons. Everytime I can I will show the stamp reference for this companies in the stamp title using the abbreviation YT# , SC# , MI# , SG#

Have fun!
