Signed hand blown smoky art glass vase with pink flecks 1973 Made in Canada

Unique hand blown glass vase. Nice smoky colour with flecks of pink and silver on upper half. Signed M. Robb '73. Appears brown but under light seems to have a green tint. Appears scratched on the neck, see last two photos. Approximately 6.5" tall and 3" at widest part. No chips or cracks. Please note: Photos are considered to form part of the description. Please review all photos. When possible, I use clean re-used packaging.
