This jersey probably dates from the 1980s. There is no maker shown anywhere on the jersey. The tag reads "100% synthetic" and "Made in Italy". It is shown as a size II but it measures 18.5 inches from underarm to underarm and 28.5 inches from the top of the collar to the bottom seam along the back.
For some reason, the Alfa logos on the sleeves are backwards except for the text. Also, the inner lining is quite coarse. For this reason, I've never worn it. Probably best used as a display piece.
