Vintage Panda Picture Puzzle Cubes from China

I am confident this was a gift from someone who traveled to China in the 70's and brought this back as a gift for me as a child. Which was a very unique thing to do at the time. Traveling to China in the 70's was not like it is today. I remember knowing that this was a unique toy at the time and that is why I held on to it. It's a simple toy. Just photos of pandas to match to the cubes. For younger children. But very cute & an example of Chinese pride. Coloring damage to bottom of box from kids.
