Overall, the lamp is in very good condition. The only thing I notice can be seen in the (15th) photo above and more below. I believe that is a slit like imperfection in the clambroth glass and not a small crack. I have provided additional enlarged photos below to give you a better view. The clear and opaque etched shade is very good condition with just a couple very minor fleabites around the inside rim. I have provided (100) photos below in the listing to give you an incredibly thorough view of this rare Sandwich Glass oil lamp.

Size:  25 1/2" (Approx. Total Height)                     21 1/2" (Shade Height)                         13 1/2" (Height to Top of Font)

Date: 1870's (Approx.)                 The burner is patented March 10, 1868 & May 6th, 1873.

I love the way the orange paint on the font goes with the blue on the base. A really pretty lamp.
