Postcards, Lithography, Prague, Stamps, Senefelder

I lithographed ie drew on stones views of Prague. I had them printed as postcards with names of the most famous beauty spots of Prague. I put a few of postage stamps from my grandfather's stamp collection, which are almost 100 years old and send my postcard via airmail worldwide - an original and rare philatelic postcard collectible
I have spruced slightly my site - I am sticking to my guns, as far as the issue mit vs used i e sent postcards is concerned.
