dang i KNEW it was Olmec, i should’ve said so. i just googled it and i was right! Olmecs were my fave. i love their heads.
The heads and other carvings are from La Venta, in a musuem/park here. The pyramids are a Comalcalco. Interesting thing there is that these are built of brick, not stone, like the other pyramids in Mexico.
