Mary of Hungary. Born in Nuremberg, Sigismund was the son of the Holy Roman Emperor, Charles IV, and of his fourth wife, Elizabeth of Pomerania, the granddaughter of King Casimir III of Poland, and the great-granddaughter of the Grand Duke of Lithuania, Gediminas.
Attach tape to back of picture. The frame should complement the color scheme of the room where it will be hung. For black and white pictures, a thin black frame goes well with a white or grey mat and a black inside border. For sunset pictures, consider a red frame with a white or cream colored mat and a red inside border.
On a 16x20 photo you should have at least a 3 mat all the way around and select a frame that is approx 1/3 the width of the matting. I would use a 3 1/2 double mat and a 1 1/4 wide frame in a color that enhances the people in the photo and also complements the mat colors. Good luck to you, go and experiment at a frame shop and see whats available.
