The title is not meant to be disrespectful, but only to highlight the incongruity of the representation with what I understand of Buddhism.
Images of Maitreya in English Wikipedia are modest and comtemplative, but the Chinese page shows one familliar image with a large, well-fed body, surrounded by riches, and a big happy grin. Where I live these representations of Maitreya are everywhere.
It is understandable that as buddhism spread to different cultures certain superficial aspects might be altered to convey ideas in different ways. Here I'm just asking about history of the change.
When and where were depictions of the Maitreya buddha first changed so dramatically?
edit: The question Why is Budai often associated with the future Buddha Maitreya? suggests to me that this is not actually a representation of Maitreya at all, which conflicts with what I remember and what a google translation of the Chinese Wikipedia page at least seems to say.
