This porthole set was inspired by Kelly's two fishing boats. Porthole pictures are 100% glass except for the lettering which is 24 karat gold. The F/V Sea Quest was made for installation in a bathroom door, so the picture was made out of opaque glass that cannot be seen through...light will still transfer. The F/V Inlet Quest was made for installation in an office door that needed at least a peephole to see through. The top part of this porthole was made with clear glass as so it can be seen through. Also, this picture is doublesided...can be seen from both sides.
