A card on single-horse carriages at the tourist areas like Nariman Point, Mumbai. It is known as Victorian carriages as it is replicating the 19th century horse carriages. Thanks Bhargav.
Three different Rs5 stamp were used; they are a personality stamp, a historic artifact stamp and a stamp depicting oil refinery. They were cancelled but the postmarks were blur. Only able to determine they were from Pune and sent sometime in April.
