U.S. COAST GUARD CUTTER MACKINAW

One postcard entitled "U.S. COAST GUARD CUTTER MACKINAW". The postcard features a color photographic image of the U.S. Coast Guard's Great Lakes ice breaker MACKINAW as taken from off of its port bow. A Sikorsky HH-52A Seaguard helicopter can be seen flying low behind the vessel no the right. The photo is credited to John Penrod. A caption on the verso reads:

This 290 foot vessel is primarily a Gret Lakes ice breaker clearing the way for oil tankers and freighters. It is also used for search and rescue and law enforcement. Built exclusively for the Great Lakes, at 74'4" wide, it is too wide for the St. Lawrence Seaway.
