One in sleeve, or box of eight. Breach @ Limekiln. Blank inside, with envelope. Size 4 3/4 x 6 1/2, A-6. The note on the back of the reads: Breach @ Limekiln Orcas are the epitome of the "charismatic species," exemplifying athleticism (with a swimming-top-speed of 50 mph) size (to 30 ft. and 16,000 lbs), and good looks, with a bold black and white pattern helpful for breaking up the whale's form underwater. The Limekiln Lighthouse is on the west side of San Juan Island, largest of the island group of its name-sake and a premier place to watch for Orcas.
