Taken by the Dallas County Sheriff's Department two weeks after the assassination.InvestigationsPhotographsSignDallas County Sheriff's DepartmentTexas School Book DepositoryDallasThese black and white photographs of the Texas School Book Depository building were part of the investigative file of the Dallas County Sheriff's Department. Deputy sheriffs were dispatched approximately two weeks after the assassination to thoroughly photograph the exterior of the Depository from all sides. Today these seldom-published images offer a unique period glimpse at the full structure, including the fire stairs, entry signage and loading dock. - Stephen Fagin, Curator The Texas School Book Depository sign over the door in this photograph is also a part of the Museum's collections. It is over 17 feet long and can be seen online (1987.001.0001). - Lindsey Richardson, Curator of Collections (2008-2020)The iconic latticework screens that are visible covering the first floor windows of the Texas School Book Depository were made of decorative cast concrete bricks known as "breeze blocks." The purpose of the breeze blocks was to allow ground floor windows to be opened for ventilation of the space while cutting down on noise pollution from nearby streets. - Stephanie Allen-Givenspollutiontions and Exhibits Manager
