Rockland Historical Society will hold its third annual Postcard Show and Sale Saturday, Oct. 10, from 10 a.m. to 3 p.m. at the Lincoln Street Center (former Rockland High School), 24 Lincoln St. Admission will be $3.

Postcard collecting is very popular in Maine, and Maine postcard dealers get together all over New England to trade and sell their wares. RHS has changed the date of its show to avoid competing with a large postcard show in New Hampshire. The best dealers like to come here because it is the only postcard show in the postcard-rich Midcoast.

Dealers’ tables will be set up in the gymnasium, and the Rockland High School Alumni Museum will be open in a nearby classroom. The Penobscot Marine Museum will sell their historic photograph prints and reproduction postcards; and RHS President Brian Harden will sell postcards from his extensive collection.

Rockland Historical Society will have a table of Old and Curious Things for sale. Those who have anything old to donate for sale are asked to bring it to the society any Tuesday or Thursday afternoon; or call Ann Morris at 594-4601 for pick up.

The society also will be selling sandwiches, coffee, and baked goods. The postcard show is its big annual fundraiser; anyone who would like to help is encouraged to call Morris.
