In the marine world, nothing is quite as popular with the general public as the tug boat. Whether it's with young children or old salty dogs, there's something that draws people to them, to the personalities they seem to evoke. And naturally, people over the years have snapped photos of them, including these two anonymous images, taken from a bridge in the 1940s or '50s, of two random tugs hard at work, a momentary slice of marine life during an otherwise ordinary, hard-working day.
Above is the Russel B. of New York, and below is the Frank P. Buchanan. I've not been able to find any information about these or the companies that owned them...if you happen to know anything, please comment!
