Phone Card/Telecard Set- US WEST "Joint Global Card Series"-Rare find

Description

This is for a Telecard Chip Card set called " A Joint Global Card Series". It consists of 4 Puzzle telecards. With one card from each of 4 different companies: 1- US West   2- GTE   3- Ptt Telecom   4- Bell Canada
issued in 1996. They come with the original presentation folder. This folder has never been opened. The chip cards have never been out of it. To show what each card looked like I had to find photos on line. They work as a puzzle meeting together at the corners to
form the earth.
