In reply to one of requests, a collector from Japan contacted me and ultimately provided me with my first example of this Stonehenge phonecard. I found two more examples on eBay.

The QUO 500 unit card is for a different phone system, it is a bit larger than the other cards, and the usage punches are on the card.
If anyone who can read the language can provide more detail it will be greatly appreciated. I have been told that they are Travel Cards but were listed as Phonecards on eBay, The QUO card has the word GIFT on the back, is it a gift card ?
