The unidentified woman is selling advertising space on her breasts, reports Metro.
For £5, clients can get their products noticed with an advert on one breast, with an offer of £9 for both.
The girl stated: "I am a beautiful young girl and I offer my breasts for greeting cards and adverts.
"Send me your message and I'll send you a pic with it written on my breasts."
Initially posted on a Czech website, the notice was later posted on Facebook where it gained popularity and became viral.
