On another site we've been discussing the finds they've made at Teotihuacan and all of them are very intriguing, including the excavation of probable Maya goods within the graves. I don't have any concrete ideas, but I'd speculate that the goods were imports - there was contact between the two cultures and providing they were amiable at least part of the time, trading would be a natural course. On the flip side of that, I'd be interested to find out, if there was trade, what the Maya imported from the Teotihuacanos. *g*
