Royals from Thailand

Jobbo sent me these postcards from Thailand. There were no clues about what the postcards represents (so maybe the information I found is not exact).

Portrait of the king Prajadhipok or Rama VII (1893-1941) which is displayed in the Chakri Mahaprasad Hall at the Grand Palace, Bangkok. He was the last absolute monarch and the first constitutional monarch of the country.

I guess this is the current royal family.

I would like I could read the stamps...
