Vintage Hand Painted Stones from Three Gorges China

Very cool collectibles from the Three Gorges in China. Unsure the year they are from, but my guess is at least the 70s (my grandmother was quiet the traveler back in the day). One of the stones has a panda while the other I believe is meant to show the landmarks of Three Gorges (please let me know if I’m incorrect!) The boxes are original (roughly translated they say “Three Gorges Stone Travel China” on them), so they are definitely looking a little worn. The stones themselves are in excellent condition
