1.  Revolving fund.  There is established within the Maine State Museum a revolving fund for the use of the museum to cover the operation of the museum sales program. The Museum Director is authorized to purchase, establish the price of, sell and restock through the museum sales program publications, reproductions, handcrafts, prints and paintings, gifts and decorative items, paper products, education materials, hobbyist materials and other items that relate to the museum's mission and programs. Income from the sale of these materials must be credited to the revolving fund to be used as a continuing carrying account to carry out the purposes of this subsection and subsection 2.  

2.  Maine State Museum Endowment for Publishing.  The Maine State Museum Endowment for Publishing is established. On an annual basis, a percentage of the proceeds from the museum sales program's revolving fund established in subsection 1 may be deposited in the Maine State Museum Endowment for Publishing to be invested by the Treasurer of State according to the laws governing the investment of trust funds. The percentage deposited must be determined by the Museum Director and approved by the Maine State Museum Commission after the director ensures that the funds remaining in the revolving fund are sufficient to sustain the museum sales program in a fiscally sound manner.
