Unknown — USA Regency 75

Added 06-30-2007

Here is an advertisement for this highly-prized model among collectors,  also known as the Rainbow 75.   I believe what I saw was a proof print so there is no characteristic date code and the actual magazine carrying this is unknown.  Still the ad's existence shows Parker's intent to market the Regency.

If you have any information about the magazine issue(s) in which this ad was placed, please email me.
