My own 1958 to 60 issue UK mono pressing of Sonny Rollins in his Freedom Suite, which takes up a whole side, then 4 lengthy tracks of improv off standards to side 2. Uk Riverside Interdisk pressing with duty stamps on the labels, which show it is early, if all the other signs were not there as well. Oscar Pettiford Bass and Max Roach drums for an Elite rhythm section behind an elite Saxophone god. I would go even further here and say late 50s Sonny is the best for me. 

Excellent record in an excellent sleeve plays excellent on my mono ortofon cartridge
