This stamp profile regarding the design of the 1935 Connecticut Tercentenary stamp and other related information, was originally published in the U.S. philatelic magazine Stamps (April 6, 1935):

April 26, 1935, has been set as the first day of sale for the new three cent Connecticut Tercentenary stamp. Hartford, Connecticut, has been designated exclusively for the first-day sale, and the stamp will be available at post offices throughout the country the following day, or as soon thereafter as distribution will permit.

The central design of the stamp, approved by the entire Connecticut Congressional delegation, will be a reproduction of the old historic Charter Oak. The stamp will be of rectangular shape, and in size, will conform with the current Special Delivery stamp – 84/100 inches by 1-44/100 inches.

The stamp will be inclosed in a single line border, and its color will be a rich lilac. In the upper left corner will be the year 1635, and in the opposite corner the year 1935. In a vertical line at the left of the stamp will be the word Connecticut, in dark Roman lettering, while on the opposite side, also arranged vertically, will be the word Tercentenary.

The figure 3c will appear in the lower corners in dark lettering, and below, to the right of the central motif, the words Golden Oak, in dark Gothic lettering. Inclosed in a narrow panel at the base of the stamp will be the inscription United States Postage, in white Gothic.

Collectors desiring first-day cover cancellations, may forward not more than ten covers to the Postmaster, Hartford, Connecticut, together with a cash or money order remittance, but for absolute safety, a money order is preferable.
