Early advertisements proudly proclaiming "Hinckley's Express Company of Jefferson Territory" gave evidence of commercial backing of the group favoring the name, Jefferson, over Colorado for the new territory. Hinckley's promotional effort certainly had some effect since covers to a number of mining camps are known with "J.T." addresses.
