Colorado: Yesterday & Today - Then & now photographs by Grant Collier and his great-great-grandfather Joseph Collier portraying the history of Colorado.

When Joseph Collier left Scotland bound for Central City, Colorado in 1871, it was unclear whether the young immigrant would make much of a name for himself. However, through hard work and perseverance, Collier developed a reputation as one of the state's preeminent pioneer photographers. Now, over a century later, Grant Collier has literally followed in the footsteps of his great-great-grandfather. Grant has traveled across Colorado taking photographs from precisely the same spots where Joseph Collier captured his images. These photographs are presented in the often-imitated but never duplicated book Colorado: Yesterday & Today.
