The presentation is like looking through a book on a computer. The CD-ROM works in PCs (WIN 2000/XP/Vista/10) and Macs and is self-starting. The images can be printed out.
The 165 historic postcards, some as photos and others as paintings ranging in age from the late 1800s to the mid-1960s, are a glimpse back to when heavy industry was in its prime in North America. The focus is primarily on the steel industry, but also includes other large industries such as copper and nickel.
