According to the vendor, the Landmark playing card was signed by Presley for a security guard who worked at the Landmark Casino, Las Vegas, which at the time was situated opposite the Las Vegas Hilton where Presley was appearing. Apparently, Presley's medical prescriptions were ordered from the pharmacy at the Landmark Casino, and the security guard gave the playing card to the person collecting the prescription and asked if Presley would sign the card as a memento.
