Just to clarify there is no stay of testing for any product that contains paint, regardless of age of the intended customer. The 90 PPM lead limit is for all consumer products not just children's items.
When dealing with an artistic painting aimed for the enjoyment of an adult there is an clause for the use of paints over the limit (basically so museums, galleries, & the rich would not have to destroy masterpieces and could sell or trade them at a later date), but when it comes to the use of paint in an art piece aimed for the enjoyment of a child the piece would still have to meet the 90PPM limit for lead as well as certain other CPSIA.
The CPSIA is a very confusing piece of legislation, with it many subsections concerning the levels in this or that if added to this or that type of product it is easy to warp your mind. Try reading the law it self, (text link)

If the language confuses you, as it does to many of us, and you really wish to pursue this line of merchandised art then you may want to consult a lawyer to interpret it for you. The SBA or state's art council may be able to refer you to one that will do the consult for free or a greatly reduced fee.
Here's some reading to get you started on understanding what interpretations the CPSC is making in regards to the CPSIA.
