This is a 100% acrylic knit. Based on the tag, I believe it's from the 1970s. The brand tag says "California," so I think it's made in the USA. Acrylic items are common from this era, but a plain crew neck is rare. Size is L. The color is a camel-like shade. It's not too thick, making it perfect as an inner layer for this time of year. As you can see in the photos, there's a faint black stain? on the front, but it's not very noticeable in person. Shoulder width: approximately 44cm Sleeve length: approximately 70cm Body width: approximately 49cm Length: approximately 63cm
