3/$40 Vintage Picture Frames

These are all in excellent used condition. The octagon frame is missing it's glass. The frame is 9.5 in x 7.5 in the picture itself would be a 4x6. It is I believe plastic or some other manmade material. The second frame with the round corners is 7.25 in high by 5.25 in, the interior glass part is just over 5.25 inches by almost 3.5 in. It is a very heavy frame. The last frame is 6.5 in tall by 5.25 in wide the glass part is 4.5 in x just under 3.5 in. It is made of metal. (I am not 100% sure if last.frame is vintage).
