Vintage 'Mine Alone' Baby Boy Blue w/ Trains-Long sleeves - size 12 mos

Description

This is a vintage 1988 infant boys light blue, Train sweater. It is a heavy gauge yarn with white 'v' details and two rows of trains on the front and back. There are also trains circling the long sleeves. There are two buttons along the left shoulder.
The only label in the sweater is the manufacturer, 'Mine Alone'. There is no information on fabric content, size or care instructions. The sweater is a heavy gauge yarn and it feels like acrylic. Not sure of the size, but it's probably around 12 months. The measurements, of the sweater laid flat are as follows:
Chest:  12"
Waist:  10"
Shoulder: 10 1/2"
Sleeve length:  10"
Center collar to hem: 11 1/4"
The sweater is in very good, slightly used condition. The sweater appears to be hand knit, and the only 'flaw' is there doesn't seem to be a hole for the button for the button closest to the neck. But the sweater can be buttoned because the knit has enough space (but it's tight.)
This is a very cute, vintage little boy's Train sweater.
