A new book, Historic Photos of Tucson, chronicles 100 years of evolution in our community. For Mike Speelman a historian, and author of the book, the photo of the 26-hour-fire at the ice plant in downtown Tucson is only one small anecdote in the history of a this city... a city that to this day has consistently built and reshaped its appearance, ideals, and industry. Producer Luis CarriĆ³n talks with the author, and the Photo archivist of the project.
