Okay, I admit it, things could get rather wild at those early furry cons.
Here is an after hours scene from ConFURence 3 in 1993
Vicky Rabbit had made her debut in the masquerade and proven to be very popular.
She was seen wandering around the con area after hours carrying a riding crop which of course led to pics like this.

Of course it should be pointed out that the fan in the pic supplied his own leash.

Y'know, with the bad lighting and the graininess of the pic it looks like something that would show up as a 'last known photo' somewhere. :)
