It’s Red Onion Brothel in Skagway, Alaska. It was built in 1897 and there were working more than 300 girls at that time serving 14,000 men who came to the town during the Gold Rush era. A man had to pay 5 dollars for 15 minutes of love. Behind the bar were 10 dolls that represented the 10 girls upstairs. As each customer would choose a doll of his choice, the bartender would then lay the doll on her back, indicating that that girl was “busy”. Once the gentleman came back down the stairs, the doll was sat upright so every customer in the bar knew that she was once again available. Now it’s just a museum.
