3.5" with lightly tinted real photo of incredible detail, without dot pattern, with text "Kennywood Park/Ideal For School Picnics." Underside has minor loss of about 30% of the black paint from the metal rim which holds the mirror into position. Mirror silvering remains Exc. Curl has word "Chicago" but the actual maker's name is printed over a cream colored area and all but unreadable; however, from a couple of letters we are thinking it reads "Cruver." Top edge of the celluloid has four near pinpoint rub marks but overall condition is Exc. and the piece displays about 99.9% Mint. The detail is incredible and the scene was shot from a slightly elevated angle. From the background to the foreground can be seen: the ramp of a roller coaster, and below this a pair of tall sliding boards, at right is pond tinted blue all surrounded by benches with many individual people clearly visible in the foreground. A boy next to a woman stands on a park bench, two men in bowler hats stroll along, a group of four girls are laughing and talking, a woman in the very foreground peers into her open pocketbook, and at far lower left are beer mugs on a counter behind a pair of men in white aprons. This park outside Pittsburgh was established in 1898 and continues to operate today. Rare and only example known to us.
