Gorgeous unique punched tin sailboat mounted in a shadowbox type frame.  Vintage handmade piece of folk art.  The frame does show wear and has a crack in the bottom.  There are specks on the inside of glass.  It does not look like you can remove the frame easily, so I did not try to take this apart.  See pictures for best description.  Estate find of a couple in Hubbard, Texas, who lived in Mexico City in the 1960s thru 1970s.  Larger punched tin piece, measuring about 21 inches long by 15 inches across and 2 inches deep in the frame.  

I cannot guarantee the glass will not break in shipment, but I will wrap very carefully.  The glass is flat, so you should be able to be replaced if needed.
