There is a new section in the website about First and Special Day covers in my collection. You will find the link on the left in the main menu. This area is not one of my collection interests but I have acquired some through time and continue to get new ones through subscription. I hope this will serve as a reference to those of you who are interested in this area.
On this subject I also would like to share a wonderful book of Mr. Kaya Dorsan, "Turkish Commemorative Postmarks (1923-2000)" which is truly a wonderful reference book.
