Curious Early French Press Photo - circa 1908

French b&w photo 7"w x 4" h, press release pasted to reverse along with a photo agency rubber stamping.  Press release in French roughly translates to "Our photo shows two monkeys Greta and Hans de Stieffeld who made yesterday a splendid voyage in airplane accompanied by their mistress".  Appears that the chimps are to ride in a Bleriot...but where's the mistress?  Very good; some paper pasting refuse covers rubber stamp.  Fascinating story here that could only happen in France!
