John F Kennedy mug cup Sylvac vintage collectible

John F Kennedy mug cup Sylvac vintage collectible in good condition. No cracks, 6 inch tall. From the 60’s and Made in England. 2899 Sylvac MADE IN ENGLAND is imprinted on bottom and also John F. Kennedy in black cursive printed. Maybe from age but couple spots on inside or if it came that way? The area is smooth and not scratched or lifted on inside by where ear area curves in. Please see pics. Also the ceramic shows a lifted bump area at inside bottom rim. And top rim looks like paint overlap. Just trying to point out everything. Quite honestly this would make a super cool plant pot!! Pretty rare and over 60 years old. Very unique. Ceramic feel to it. Smooth. One pic shows search results…
