On November 11-12, 1961, the third PENPEX and second annual show was held at the Recreation Center in Palo Alto, California. Show hours continued to be Saturday 10:00 am to 10:00 pm and Sunday 10:00 am to 6:00 pm.
The show was chaired by Cy Thompson and supported by four local clubs: Palo Alto Philatelic Society, Palo-Menlo Stamp Society, Peninsula Stamp Club, and Sequoia Stamp Club.
The show theme was The Land of the Courtly Dons – El Camino Real “The King’s Highway” and special show cachet could be purchased for 15¢ each or seven for $1.00. At the time, first-class mail rate was only 4¢. For the first time, a special PENPEX Station cancel was created by the USPS for use during the show.
The local newspaper reported that 1,500 or more visitors attended PENPEX. The show had nine dealers, the furthest being Album Service, that came from Soledad and Marden Ross who came from Oakdale. Both had traveled 110 miles. The USPS was also present.
Possibly the exhibits brought people to the show. There were 180 frames of 4 pages each.
A complete History of PENPEX exhibit will be on display at PENPEX 2011 on December 3 and 4 at the Community Activity Building, 1400 Roosevelt Avenue, Redwood City. The stamp show is free and open to the public.
