The History News Network had a 2003
report mentioning this painting:

"The New York Metropolitan now attributes to other artists three of its "Goyas" - including a copy of Las Majas en el Balcon (The Girls on the Balcony), the original of which is privately owned in Switzerland."

The Metropolitan Museum web site page on this painting is here.

"......the penetrating but also mischievous glance of the two women as they muster the passing parade achieves a riviting liveliness. One feels compelled to pay them an acceptable compliment or to gain their attention and approval in some other way."
Fred Licht, Goya, published by Abbeville Press, Page 116
