SEARSPORT — Historic images from Penobscot Marine Museum’s collection of over 140,000 photographs will be available at the Maine 2015 Antique Paper Show from 8:30 a.m. to 3 p.m. Saturday, June 27, at the First Congregational Church Vestry, 8 Church St.

The show complements the museum’s photography exhibit, “Exploring the Magic of Photography: Painting with Light,” which includes a gigantic walk-in camera obscura.

Penobscot Marine Museum’s collection of historic photographs began with a collection of negatives from a turn-of-the-19th-century postcard company, Eastern Illustrated & Publishing Company of Belfast. Postcards, which were popular in the late 1800s and early 1900s, and their glass plate negatives still have a significant presence in the museum’s collection. They paint a picture with words as well as images of life a hundred years ago.

The Maine 2015 Antique Paper Show: Postcards and Paper Collectibles includes thousands of vintage postcards, old maps, historic photographs, sheet music and paper ephemera. Free appraisals for paper collectibles will be available from 1 to 3 p.m. Admission is $2, and includes $2 off a Penobscot Marine Museum admission ticket.
