Tuesdays Thrift Store Finds

I was looking around my favorite neighborhood thrift shop and was thrilled to find these two pencil signed and numbered Salvador Dali lithographs proped up in the back corner of the store.The first one is titled The Resurrection. And the 2nd id The Immaculate Conception. They are signed in pencil. Bottom left with the following I-L III/CL and. Bottom right the Dali. Signature. I believe they date from the 1970s but not sure. Any info will be appreciated.
