I have been collecting stamps and other materials for 45 years. I have around 2 million stamps and thousands of ephemeras. My main areas of interest are Ottoman, Turkey, GB and Commonwealth, Russian Empire and early USSR, German Reich and German States, Italy and Italian States, France and Portugal, including their colonies. I also have a nice collection of China and Japan.
My ephemera collection is quite remarkable. Envelopes with black penny, blue penny and other Queen Victoria stamps, old Ottoman, Italian, German and American postcards, envelopes, old maps in Arabic and Ottoman, thousands of other documents.
