Narrative:
I had assisted with the r-hand thrust reverser. I was called at the last moment and I brought out the operations check and the fim. I had the flight crew go through the operations check. The r-hand thrust reverser message didn't clear. Therefore; MEL was issued. I had the upper thrust reverser lockout and icv pinned. I also installed the placard and turned off the thrust reverser switch as required. Then the next day I was informed that I didn't have the lower thrust reverser lockout installed; only the upper thrust reverser lockout. Furthermore; the placard wasn't written in red ink. The flight crew was doing their preflight check the next day. The pilot inquired about the lower thrust reverser lockout was missing as per MEL and the placard not written in red ink.
