Chronic myeloid leukemia (CML) is a rare type of blood cancer and occurs when the bone marrow makes too many of one type of white blood cell, called myeloid cells. Almost all CML cases are caused by an abnormal chromosome called the Philadelphia chromosome.
These are new 18X24 Quality Picture Mats. The Openings are Bevel cut 12.5 x 18.5 to fit a 13X19 photo or print. These mats are cut from Quality white core mat board and are excellent for framing photos or prints.
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.
