Pyrex Cinderella Mixing Bowl Set, Butterprint Pattern (not authenticated)

This set consists of four nested milk glass Cinderella-style mixing bowls featuring the turquoise and white Butterprint pattern, characterized by stylized depictions of a farmer, his wife, corn, and chickens. The bowls showcase a two-tone color scheme where two bowls are turquoise with white print and two are white with turquoise print, each designed with distinctive dual pour spouts and handles characteristic of the Cinderella line. Physical characteristics include smooth interior surfaces and glossy exterior finishes displaying the repeating atomic-era graphic motif. The pieces appear to be in good vintage condition with minor signs of handling or surface wear consistent with age and domestic use, though no maker's stamps or backstamps are clearly visible in the provided image. The attribution to Pyrex is based entirely on the iconic form factor, Cinderella handles, and the well-documented mid-century Butterprint pattern, often associated with production from the 1950s or 1960s. This unverified identification rests strictly on visual similarities to known Corning Glass Works catalog items, and the items remain unauthenticated.

Based on what I can see in the photograph, this set of four nested mixing bowls displays the iconic turquoise and white Butterprint pattern and Cinderella silhouette commonly associated with mid-century Corning production. I cannot verify from a photo alone whether these pieces are genuine, as visual characteristics like milk glass forms and screen-printed patterns can be replicated. Without physical inspection, I am unable to check for maker's stamps, backstamps, or glass quality markers that typically aid in evaluation. The value estimate provided assumes the hypothesis that these items correspond to the popular Pyrex Butterprint line from the 1950s or 1960s in good vintage condition. Mid-century kitchenware, particularly matching nesting bowl sets with atomic-era motifs, generally enjoys steady demand among collectors, which forms the basis of this price range. However, this estimate is contingent upon proper verification. If physical inspection reveals the pieces to be modern reproductions, contemporary replicas, or unbranded items produced 'in the style of' the classic pattern, the market value would drop significantly, likely to the $30-$60 range. To confirm the attribution and secure full market value, an in-person examination by a specialized appraiser and verification of any potential base markings or manufacturing idiosyncrasies would be required.
