Photo Caption:

The 1st order Fresnel lens from the Navesink Lighthouse is shown here in the Lighthouse Service exhibit at the 1926 Sesquicentennial Exposition. If you look closely to the far left of the photo there is a unique cut-open model of a lighthouse tower with a dory hanging from it to show what the inside of a light tower looks like.
