1967 Simplicity Pattern Gown & Pajamas w/ Fabric Child Sz 4

This is a 1967 Simplicity pattern #6815 for child size 3 night gown, or pajamas in two length.My mother bought this pattern in 1967 and some material to make my 4 year old niece some pajamas. She trimmed the pattern pieces and pinned to the material and cut it out, but for some reason she never finished it. My niece is now in her sixties. We found this when going through Mama's sewing stuff years ago, and then I put it up and forgot it. So now I'm offering it to someone to finish for their little girl. The fabric is a lightweight -not sure what it is made of, but it is pretty pink floral print. I did see one stain (probably due to storage and age-hopefully it will come out easily). I tried to show all the pieces. If you have any questions, just send me a message. Also, the last picture is of the sales receipt. Mother bought it from J. C. Penney's, she worked there in the fabric department for about 20 years.
