Doostane Farsi Zabane Man, which translates from Persian (Farsi) to "My Persian-Speaking Friends," aims to increase friendship and cultural understanding between Iranians and Americans through a pen pal program between young citizens of Iran and the United States.
Unfortunately there is no website or a dedicated place to Iranian paintings from that era but you can google “Qajar era art” or “Persian miniature”. You can find a great number of paintings from 1800’s that way. Good luck. i wish I could help more.
