Santa Catalina Island, California - North End of Avalon Bay

This unused Mitchell postcard above, shows the untarnished Avalon Bay in the late teens or early twenties. It is at this location that the famous Casino Ballroom was built in 1929.

1923 Great Kantō Earthquake

I found this unused Japanese postcard while going through my box of "yet-to-be-sorted" cards. I don't have many foreign cards in my collection but thought this one to be interesting. Some background below regarding the quake.

This earthquake devastated Tokyo, the port city of Yokohama, and the surrounding prefectures of Chiba, Kanagawa, and Shizuoka, and caused widespread damage throughout the Kantō region. Its force was so great in Kamakura, over 60 km (37 mi) from the epicenter; it moved the Great Buddha statue, which weighs about 93 short tons (84,000 kg), almost two feet. Estimated casualties totaled about 142,800 deaths, including about 40,000 who went missing and were presumed dead.

Groton Monument - Groton, Connecticut

This undivided back postcard was published by the Hugh C. Leighton Company in Portland, Maine. Printed in Germany most likely between 1901 and 1907..

The Groton Monument, sometimes called the Fort Griswold Monument, is a granite monument in Groton, Connecticut. It is dedicated to the defenders who fell during the Battle of Groton Heights on September 6, 1781. 

The Battle of Groton Heights (also known as the Battle of Fort Griswold, and occasionally called the Fort Griswold massacre) was a battle of the American Revolutionary War fought on September 6, 1781, between a small Connecticut militia force led by Lieutenant Colonel William Ledyard and the more numerous British forces led by Brigadier General Benedict Arnold and Lieutenant Colonel Edmund Eyre.

S.S. North American - The Georgian Bay Line - Chicago

SS North American was a Great Lakes steamboat built by the Great Lakes Engineering Works at Ecorse, Michigan in 1913 for the Chicago, Duluth & Georgian Bay Transit Company. The vessel was launched on January 16, 1913 and was the oldest of two sister ships, the newer one being the SS South American.

While the North American was on the North Atlantic being towed to Piney Point, she unexpectedly sank on September 4, 1967. The location was 25 miles (40 km) northeast from Nantucket Light, where the bottom is at 400 feet (120 m). The wreck still remains at this location.

I suspect that this unused chrome postcard is from the late 50's, early 60's. 

Winona Assembly and Summer School - Winona, Indiana

In 1894 The Presbyterian Church of Indiana purchased the land, a transaction that was negotiated by Solomon C. Dickey. He would become an honored figure in Winona Lake. Dickey established the Winona Assembly and Summer School in 1895. 1915 brought a significant setback: financial ruin. Due in part to losses in railroad revenue, the Assembly was forced to declare bankruptcy.

Float Fishing in the Missouri Ozarks

An unused linen card from the Blair Cedar & Novelty Works in Missouri which is the world leader in the production of cedar products and is still in business! 

Not sure why, but this card makes me think of the movie Deliverance...is that Ned Beatty in the bowler?  :D

The Flying Yankee

The Flying Yankee was a diesel-powered streamliner built in 1935 for the Maine Central Railroad and the Boston and Maine Railroad by Budd Company and with mechanical and electrical equipment from Electro-Motive Corporation.

The eventual goal is to restore the train completely to running condition. The train was moved to Lincoln, New Hampshire, on August 10, 2005, to the Hobo Railroad where the mechanical restoration is taking place.  More info at:  http://www.flyingyankee.com/
