Age of Mexican Pottery?

Hi!.....This is a Estate sale purchase from several months ago for about $35....it looks as though it may be Mexican Pottery....??..Its approximately 8.5 in ht x 5in width..Its in good condition....it does have the dark spots that are supposed to be manganese deposits but I'm not sure if they are authentic.....If someone has any information on the age...please feel free to share your thoughts.....Thanks!

 

Please post new photos without the flash.

 

Yes, it is difficult to see the designs, and to tell what parts of the surface are actually white vs glare.

That said, 99 times out of 100 (or more), "precolumbian" ceramics found on the open market are copies/reproductions/recreations made within the last century. Yours appears to be loosely based on Mayan and other gulf coast styles (Huastec, Olmec). The surface appears to be artificially applied, and manganese spots have been recreated for many years.
