The author describes three case histories relating to recently developed techniques in Mexico for packing and transporting works of great cultural importance. The first refers to improvements in packing cases where the reinforcements are more effectively designed. Here, polyurethane foam is used as a cushioning material. The second expenence describes a specially designed polyester glass fiber case reinforced with steel members used for safely transporting precious ecclesiastical robes to Chicago. A system of interlocking trays with polyurethane fittings was employed. The final case history is the transport of a massive Olmec head to Spain by air freight in which the author describes the support and handling systems. -- AATA
