During the 1970s phone subscribers were permitted to own decorative housings for their phones for the first time.
Imagination sets, introduced in 1977, were Northern Telecom's line of decorative phones. 

The line was distributed in the US through NT's country headquarters in Nashville, TN and using distributors,
such as TeleConcepts, North Supply and Centel.

This page contains photos and info from NT and distributor catalogs
with a few additions from my collection and photos from site visitors.
It is presented as a reference to help identify some of the models sold in the 1970s and early 80s.

Early sets were hardwired.  Later sets had modular connectors on handset and line cords.

The American Club Ltd. provided upscale versions of the Contempra sets made in Nashville, TN for the American market.

Handsets were covered with leather and housings and handset faces were painted in patterns to simulate wood or marble.

Sets were finished with engraved brass "Limited Edition" plaques on the bottom and packaged in fancy boxes.

The paint typically shows wear on the handset and cradle from use, often revealing the color of the plastic underneath.
