Vintage Smirnoff Leaves You Breathless Street Lamp  

I have a vintage lamp that says "Smirnoff Leaves You Breathless" written on the shade. The lamp is black and looks like a replica of an old street lamp. It works and is in good condition. It is between 5 and 6 feet tall.
From what very little I've learned, the ad campaign was launched in the 50s.
I purchased it from an antique dealer in the early 90s for $50.
Can anyone PLEASE tell me anything about this lamp and what it might be worth. I would like to sell it, but need to know more about it.
Thanks in advance!
