The maid recalls cleaning his room while he was performing. Maid told my aunt that while cleaning Elvis room at the International Hotel she noticed the Pepsi Cups and Quartz clock and International Stein/Mug and asked someone from Elvis Entourage if she could have them, they said sure you could have them. The specific individuals responsible for daily housekeeping were generally Hotel staff whose names were not typically public information unless they shared their experiences later. Access to Elvis's personal suite was likely restricted to a small, trusted circle of staff and his entourage, the "Memphis Mafia".
My Aunt willed these to me in 1980. I've had these collectibles in my possession since 1980.
