Any info on artist of painting(?) or print signed William Henry '46 ?

I found this today in a box of new donations to a friend's thrift store.
I can't tell if it's a painting or a print though I'm leaning towards print (under a magnifying glass I can't see any pixels but the image isn't sharp either - maybe the glass covering it is the blurred kind?
More important, can anyone tell me who the artist William Henry is?
Any help would be greatly appreciated.

 

appears to be a lithograph

 

This guy.

"William Henry (American, 20th C.) Signed to bottom right corner "William Henry" as well as dated "60"; measures approximately 39-7/16" x 31-5/8" with frame and has a sight image of approximately 25-5/8" x 18-3/16"; in Fair overall condition with some foxing. William Henry resides in Naples, and is regarded as "Bill" by most. He started doing watercolors in the Bahamas where he lived for eight years. During that period he did a mural for the Duke and Duchess of Windsor, at the time of the Duke's governorship of the Bahamas. (This was among the possessions afterwards moved from the Windsor's Bahama residence to their more recent home in the outskirts of Paris.) In the interim, many Henry pictures were purchased by notable collectors including Mr. Carmen Messmore, director of New York's Knoedler Galleries, the late Lord Duveen of Duveen Galleries, Sir Gerald Lysaught of London, the Firestone Collection, the Woodward collection and the Schoonmacher collection (which has eighteen Henrys). The first one-man show accorded Bill Henry opened in New York at Delphic Galleries on 57th Street. World history was made also that day --Pearl Harbor Day. From 1942 to 1946, the army claimed Bill Henry. He was captain in the Corps of Engineers, attached to the Air Force. For five years following the war, Henry painted Jamaica, Key West, Mexico, Nova Scotia and the Gaspe Peninsula. He returned to Florida in 1951 where he again engaged in the creation of murals, many of which have won acclaim both here and abroad. Now living in Naples, Henry's exhibits have become notable features at the McNichols Galleries. One of his latest murals adorns the south wall of the main lounge of the Port Royal Beach Club. This was chosen in competition with some of the nation's foremost mural artists."

Hard to believe it had an estimate of only $60 - $80!
Do you think mine is a watercolor? I may remove it.frim frame/glass to know for sure.
Thank you Debora!

 

I'm a bit puzzled. I keep finding what appears to be like yours that they say is a Buell Whitehead lithograph titled William Henry's Boat.

Here is an example

It does look like it! The signature? Is right on edge of lower frame - so I'm going to take it out to see what's underneath
Thank you!
