Here we have two cheeky little misses. The booth chair being too low, makes them appear to be very, very small and almost pixie-like. Adding to that impression is the goofy gap-toothed smile on one and the cute freckles on the other.
With two similarly, badly cut fringes, (“Gee, thanks Ma!”), I would suggest they are sisters. But of course they could be best friends with a penchant for playing hairdresser with mummy’s dressmaking scissors.
This strip is from the USA and probably dates to the late 1960s or early 70s.
