Thank you for contacting Mearto with your appraisal inquiry.
This is a bit of a shot in the dark because I can't find the age when Dewar's used this particular packaging, nor which variety of scotch is included. Because so little is known about the bottle inside, I've marked this conditional.
Based on the photos and information provided, and subject to examination, this is:
A vintage gift-presentation bottle of Dewar's Scotch
Indeterminate age or proof
retained in its original cardboard box with blue and white (black and gold?) decoration in the form of a highlander with thistle
12 inches high, bottle probably 750 ml
*represents a fair-market value for auction purposes; retail or asking price may vary.
Please let us know if you have additional items to appraise, and thank you again for using Mearto.
