As a category of exhibits, replications are methods for recreating the "real thing". Unlike the recordings of the "real thing", like photographs, which show the real thing as it exists in real life, replications start from scratch and recreate or build a "copy" of the real thing. For example, animations are produced using very sophisticated computer software that can combine many forms of data with color and perspective to create a very lifelike reconstruction.

Separated by vast gulfs of political, cultural, and philosophical divergence, the three chief Allied nations of World War II - the United States, the Soviet Union, and Great Britain - attempted to formulate a joint policy through a series of three conferences during and immediately after the conflict.

Physical objects and substances are the "real thing". They are the physical things that are at issue in the case, such as defective parts, pieces of fabric, preserved specimens, and contaminated substances. They can be highly effective exhibits, so the establishing the foundation and preparing to defend against objections needs to be done carefully. Avoid common mistakes in laying an adequate foundation and prepare to defend against objections.
