Postal History Cover Mailed in Lousiana in 1885

I believe this cover was mailed from Dickson's Cross Roads in Lousiana to Shreveport LA in 1885

Interesting killer marking on stamp.  Want to know more about postmarks?  I learned a lot from the book listed on Amazon about Postmarks on Postcards (the information is good for covers too.)  I bought the kindle edition and the illustrations are pretty good.  The actual book would be nice too.  There are chapters on identifying cancellations by machine or hand. The most interesting part was about killer bars or marks made on the stamps.Below is the link to Amazon for this book.

Pocalla Springs Tourist Court Postcard Sumter South Carolina

I like all the small boxes and different views on this postcard...here swimmers are enjoying the swimming pool which is supplied by Artesian wells and Springs .And the resort is famous for its drinking water.  Also available is camping spots in addition to the brick cabins.
It says there is ample grounds for House Cars or Tents.  I wonder if House Cars are the first RVs.    This postcard was mailed in 1936.

This is another motel postcard from the 1950s - RANCHO 101 MOTEL...on the coast highway in San Diego California. on Highway 101.

Mount Rushmore, South Dakota, Pair of Linen Postcards

From looking at these two postcards I would say that the Presidental Carvings are not complete.  There appear to be cranes on the top.  I looked at some finished photographs of Mount Rushmore in South Dakota that they look a little different. 
With Presidents Day this month I thought it was an appropriate pair of postcards to share.
