Ceramic mug with mountain landscape graphics

This item is a ceramic mug featuring a dark teal or navy blue interior and exterior base color. The exterior is decorated with a wraparound graphic depicting a stylized mountain range under a celestial sky. The illustration utilizes a limited color palette of ochre, sage green, and various shades of blue and teal, featuring a large circular sun or moon behind jagged peaks and silhouettes of coniferous trees. Small white specks in the upper portion of the design suggest a starry sky. The mug appears to have a slightly flared rim and a square-shaped handle attached to the right side of the body. While the user-supplied note identifies this as a 'starbucks mug,' there are no visible brand logos, trademarks, or manufacturer stamps on the visible portions of the vessel in this image to verify this claim. The design is stylistically consistent with contemporary commercial drinkware often produced for coffee house chains or souvenir shops. The finish appears glossy, and the item displays no obvious chips or cracks in the photograph, though its physical integrity and bottom markings remain unexamined.

I have examined the digital image of the ceramic mug, which features a contemporary mountain landscape graphic with a celestial theme. Per the user's submission, this is identified as a 'starbucks mug.' Based on what I can see, the design is stylistically consistent with modern commercial drinkware produced for major coffee house chains, though I cannot verify this claim from the photograph as no manufacturer stamps or trademarks are visible. For this appraisal, I am proceeding with the hypothesis that this is a mass-produced item from a recognizable retailer like Starbucks. The suggested value range of $10-$25 is based on typical secondary market interest for decorative corporate merchandise in well-maintained condition. I cannot verify the item's physical integrity or the existence of bottom markings from a photo; therefore, this estimate assumes the surface is free of micro-fractures or structural defects. The value of such items is largely driven by collector demand for specific series or local editions. If this item were confirmed to be a generic souvenir mug rather than a branded piece, the value would likely decrease to the $2-$8 range. To confirm this attribution, I would need an in-person examination to inspect the base for a brand hallmark and to check the weight and glaze consistency. This value estimate assumes the item is an example of the branded merchandise suggested by the owner; however, without physical verification of a logo, this must remain a working assumption for valuation purposes only.
