I've never seen this ink before, a flattened dome with early font embossing and a crude shear top.
Embossed: BILLING'S / MAUVE INK
Height: 2" (x 2 3/4" wide)
Color: aqua
Condition: very nice - structurally perfect except for slight roughness around the shear lip, as is usual for shear tops. Pretty clean, just trace haze.
Reference Number: GW263
