Yeah, these look to be castings rather than carvings by looking at the edges of them... Prolly knockoffs but, hey???

When I took art history the first semester went from the beginning of time up to the 19th century and the second semester the last 100 or so years so we didn't really spend a lot of time back then so I really can't help much except to guess that they are from Thialand which pumps out alot of stuff... I have some of it myself...
