These are great for couples. The 72 piece photo circle jigsaw puzzles are great for photos that are taken horizontally or vertically. I think that most professionals seem to photograph people and especially couples in a portriat or vertical shot. Think of most photographs that you see in magazines they seem to be take in a vertial or portriat mode. By the same token, I think that most home photographers hold cameras level and as such the photos are horizontal or landscape in nature. Either way, the circular shape of the circle jigsaw puzzles allows a photo of any orientation to be placed in it and look great. You don’t need a sense of the background either. Photos of couples, kids, family and pets seem to pop on the photo circle jigsaw puzzles.
