Today I received a nice cover from a friend in India, Singh. He picked four commemorative stamps of architecture and cultural theme for me. Thank you, Singh! :D
Three stamps on the upper-side from left to right (1-3) and a stamp on the bottom-side (4):
 The Doon School, Dehradun (2010)
The Doon School is very well-known and among the best Schools in India, located in Dehradun in the state of Uttarakhand. Doon School was established in 1935, it was founded by Shri Satish Ranjan Das, a prominent Kolkatta barrister inspired by the British Model Public Schools.
 Cathedral & John Connon School, Mumbai (2010)
The Cathedral and John Connon School is one of the most prestigious educational institutions in India. For the past 150 years it has imparted the finest education through the medium of English, and has the tradition of upholding the most worthy values of the civilized world.
 Rath Yatra, Puri (2010)
The biggest and the grandest of all festivals in India. The highlight is the sacred journey of the statues of the Lord Jagannath of Puri with brother Balabhadra and sister Subhadra from main temple to Gundicha Temple, where they remain for nine days. The mammoth wooden chariots carrying the three deities pulled by thousands of devotees, present a spectacular scene. The yatra (journey) begins on the second day of the lunar month (asadha).
 Central Bank of India (2010)
Established in 1911, Central Bank of India was the first Indian commercial bank which was wholly owned and managed by Indians. The establishment of the Bank was the ultimate realisation of the dream of Sir Sorabji Pochkhanawala, founder of the Bank.
