By bus to Istanbul, then by bus to Tehran, afterwards to Kerman and Zahedan... by bus, of course. Then by a taxi to the Pakistani border, by bus to Quetta and then by train to Rawalpindi. One can get there in less than ten days!
Please excuse the quality of the photographs. I was a very inexperienced photographer to say the least and both the camera and the scanner had a few glitches of their own. The pictures have mostly historical value for me.
