This particular poster became a conversation piece among visitors of the station as well as fellow colleagues. Since I didn't know anything about the group, I used to tell people the poster was a personality test to identify what type of girl a guy was most attracted to -- similar to those early BuzzFeed articles ("What your favorite female Friends character says about you!"). To me, Mulberry Lane resembled a more tame version of the Spice Girls with each member possessing personality types such as flirty, girl-next-door, sweet, and wild.
Two years later, I changed positions within the radio station and I don't know what I did with the poster (let's assume I threw it away), but the inside joke continued. To this date, my former boss still forwards me all the emails she still receives from Mulberry Lane wishing their fans a Merry Christmas.
