Cobalt blue glass mug featuring a Shirley Temple transfer

This item is a short, handled drinking mug crafted from translucent cobalt blue glass, appearing consistent with mid-20th-century pressed glassware. The front of the mug is decorated with a white decal or screen-printed portrait of a young girl with ringlet curls, which includes a cursive facsimile signature verbatim reading "Shirley Temple" at the base of the image. The mug features an angular, hexagonal-style handle and a slightly tapered body. The craftsmanship is consistent with Depression-era or post-Depression souvenir glassware, such as those historically produced by companies like Hazel-Atlas, though no manufacturer's mark is visible in the photograph to verify a specific maker. The color is a deep, rich blue with some optical distortion visible through the glass. Regarding condition, there appears to be some minor surface wear on the white decal, and the glass rim shows slight irregularities consistent with pressed-glass manufacturing. Without physical inspection, it is impossible to determine if this is a period-correct piece from the 1930s or a later reproduction; however, the style and subject matter are characteristic of advertising premiums from that era.

Based on my visual analysis of the provided image, I have evaluated this cobalt blue glass handled mug featuring the likeness of Shirley Temple. The item appears consistent with depression-era advertising premiums, such as those historically associated with Hazel-Atlas or General Mills promotions. Based on what I can see, the deep blue color and the decal's cursive facsimile signature are hallmarks of this specific type of collectible glassware. However, I cannot verify from a photo whether this is a period-correct piece from the 1930s or a later twentieth-century reproduction. A physical inspection would be required to analyze the wear patterns on the glass base and the specific application method of the white transfer to confirm its age. My estimate of $15.00 to $35.00 applies to a mid-20th-century piece in the observed condition, which shows some minor loss to the decal. The market for mid-century celebrity-themed glassware remains stable among nostalgia collectors, though prices vary based on the clarity of the image and the lack of chips or 'flea bites' on the rim. Should the item be identified as a modern replica or a contemporary 'in the style of' piece, the value would likely decrease to under $10.00. To further refine this valuation, an in-person examination by a glass specialist or the presence of documented family provenance would be necessary to support its historical context.
