Elvis Presley's remaining two jets have been put up for sale.

Estate officials at Graceland asked the current owners of the Lisa Marie and the Hound Dog Ii to find a new home for the planes in July (14) after deciding to exercise their option to end a 30-year agreement to keep them at the Memphis, Tennessee tourist attraction.

Owner K.G. Coker recently started negotiations with estate officials to keep the aircraft at Graceland, but the talks have since failed and Coker is now seeking to offload the jets.

The advertisement for the planes does not list a price, but the future owner will not be able to fly them, as Coker explains, "They're both museum pieces."

The Lisa Marie and Hound Dog Ii, which have been on display at Presley's mansion since the mid-1980s, will no longer be among the attractions at the Graceland estate from April, 2015.
