Vintage ADOT 'NO PETS ALLOWED' Metal Sign

This is a vintage ADOT (Arizona Department of Transportation) warning sign, specifically a 'NO PETS ALLOWED IN THIS AREA' sign. It measures 14 x 14 inches and is constructed from a metal panel, likely aluminum or steel, given its common use for outdoor signage due to durability. The sign features a white background with bold, black capital letters and a thick black border with rounded corners. The text is centrally aligned and reads 'NO PETS' on the top line, 'ALLOWED' on the middle line, and 'IN THIS AREA' on the bottom line. The physical characteristics indicate a utilitarian design, typical of official public signage. Observable condition issues include significant wear consistent with outdoor exposure and age. There are numerous scratches, scuffs, and areas of discoloration, particularly noticeable on the white background, suggesting environmental weathering. The edges show signs of chipping and minor bending. Critically, there are four visible mounting holes. The top two are somewhat oxidized, but the bottom two exhibit heavy rust and corrosion around the holes, especially the one on the bottom right, which also has a washer or bolt head that is heavily corroded, indicating it was likely mounted with steel fasteners. The overall patina suggests a considerable period of use. The craftsmanship appears to be industrial standard, with machine-cut elements and screen-printed (or similar) lettering, designed for clarity and longevity rather than artistic merit. The manufacturer details provided ('ADOT SIGN FACTORY') confirm its governmental origin, and the 'REQP: 70918' is likely a requisition or batch number. The estimated age would be several decades old, given the visible wear and the style which predates modern digital printing techniques, likely mid to late 20th century. Its robust construction and clear message reflect its purpose as a functional piece of public infrastructure.
