India postal history lot 9 postal stationery cards & 6 covers KEVII postmarks

This is a lot of 15 assorted postal history items from India in the early 20th century.  It consists of nine postal stationery cards and six small covers/envelopes, all with pre-printed KEVII stamps. They may be all commerical correspondence.

The postmarks appear to include Sikar, Bamgari, Parbatsa, Ringas, Fazilka, Jaipur, Sironj, Indargarh, Kotah, Dera-Ismail-Ka, and Cawnpore, as well as others I cannot distinguish.

The cards and covers are in fair condition with some wear to the corners and edges, a few marks, some creasing, and some minor loss, as seen in the photos.  Some of the postal stationery cards are horizontally creased.
