I'm a computer engineer. Now I'm teaching in a college.
My lifetime hobby is stamp collecting. When I was about eight years old, my mother brought me some used stamps from her colleague. This is my first collection.
My theme is computer and related.
I'd like to use my duplicated computer topic stamps,P.R.China stamps,USSR stamps,etc. to exchange with you.
