In Tucson we are lucky enough to have THIS - which in based on Mexican traditions - but incorporates many other culture's Day of the Dead-type rituals - such as *Japanese*...(and even personal expressions...some of which are pretty amazing and creative...)

This is the St. Nicholas Cemetery in León, Guanajuato:

A while back I posted about South Texas artist Cayetano Garza. The guy loves blending classic cartoons with religious iconography - particularly anything inspired by Dia de los Muertos. I cannot recommend this guy's stuff enough.

I post pictures of Day of the Dead artwork and photos on my Halloween tumblr—making sure to differentiate between the two. One of the artists you didn't mention is Sylvia Ji, who happens to be one of my favourite artists.
