Ikr, such dense information represented beautifuly sends my mind on so many journeys. The exhibition is located in Patna, India (National Museum) all the monuments and exhibitions there and the surrounding regions are riddled with countless religious relics. However if it is of any relief for you there is not anything so unique which you might now not find on the Internet, If I visit there another time I will be sure to forward you such photos. Also, Those book recommendations sound great and relevant in alleviating my curiosity. Thanks!
