Where can I get a knitting pattern for an all-in-one long sleeved cardigan no seams no joins?

Elizabeth Zimmerman created the Baby Surprise Jacket over 50 years ago & then the Adult version a few years later. If you Google either Baby or Adult Surprise Jacket, you will be able to easily find the pattern. This is a side to side pattern that you make completely on the needle. When you finish casting off, you can put it on.
