Yes, 'Mobley's Message' on Esquire vinyl is quite a rare one. Issued in the late 50s in very limited quantity by London based Esquire Records, who had the UK license to Prestige issues at the time. There should be 'RVG' in the runout and the sound quality will be excellent. These issues usually sound far superior to the Prestige/New Jazz issues of the time.
I've got a good number of them but - alas - no 'Mobley's Message'.
