The document discusses a 1953 book called "Big City Workers" that describes workers delivering coal by barge in New York. Upon closer examination of the picture, it appears to show the George Washington Bridge and a lighthouse. A reverse Google image search revealed the lighthouse is the Little Red Lighthouse, the last in Manhattan located under the bridge. The lighthouse was the subject of a beloved children's book that helped save it from being overshadowed by the newly constructed bridge, and it remains a landmark today.

1. Big City Workers, published in
1953 is a look at another time. On
the first page, chapter one, the text
explains workers on this barge
deliver coal to "keep us warm.”
Look closer at the picture…this is
New York, and, isn't that a
lighthouse? I’d like to find out
more.
What's the story about this?

2. A Google Reverse
Image Search reveals…
It is a picture of the George
Washington Bridge, and
under the bridge stands the
Little Red Lighthouse, the
last in Manhattan.
Visually similar images, such as the one
above, were found by adding keywords,
"lighthouse, bridge, New York" to the photo
I had plugged into Google image search.
Turned out, there's quite a little story
behind it.Source: forgotten-ny.com

3. The Little Red Lighthouse is a
beloved children’s book about a
little red lighthouse who fears it
will be overshadowed by the
George Washington Bridge when
it was built. Who knew a reverse
image search would reveal a
beloved icon? The book saved the
lighthouse and today it is a
landmark and national treasure.
