Sunday Stamps: the letter "I"

 Good day and welcome to my blog.  It's a bit chilly in the American Midwest for the end of March.

It's time for Sunday Stamps, and the letter this week is "I".

I have some older stamps from the USA showing various Industrial processes:

This series of stamps was called Building a Nation.  I have shared these before, and in my old blog post I wrote:

This is a group of four stamps from a larger set.  Most of the photographs were taken by Lewis Hine, a famous photographer.  According to Wikipedia, "Lewis Wickes Hine (September 26, 1874 – November 3, 1940) was an American sociologist and photographer. Hine used his camera as a tool for social reform. His photographs were instrumental in changing the child labor laws in the United States."
