S.A.S.E. is an abbreviation for "self-addressed stamped envelope." Arts organizations often ask artists submitting work for exhibitions, etc. to include S.A.S.E. In this way such organizations save themselves time and expense meeting their responsibilities in replying to submissions, and perhaps in returning materials as well. Information from arts organizations sometimes includes disclaimers of responsibility to return materials. Although artists should expect to receive replies and the return of their materials in a timely manner, whenever assurances of such practices are not received, it's wise to inquire.
