Authenticity is a mixture of knowledge, behavior, and material culture that permits us to collectively feel in touch with a particular moment in time. We base all three in primary and secondary sources, tempered with common sense. Above all, we believe the most important factor in authenticity is a willingness to improve with experience, not how much money has been spent. If we cannot perform an impression to this standard, we will decline doing so altogether. As a general rule, we ask new members to start with the basic items at a high level of quality, and build from there.
