PA-318 1948 (Pennsylvania) Coffee Mug - Design

This coffee mug features a classic piece of Pennsylvania road signage: the PA-318 route marker, as it appeared in 1948. The design is a faithful reproduction of the official state highway shield from that era, making it a perfect conversation starter for anyone who appreciates vintage Americana and Pennsylvania history.

Key Visual Elements

The central element of the design is the iconic keystone shape. This bold, stylized keystone, rendered in its classic form, is a direct nod to Pennsylvania's nickname, "The Keystone State." Within the keystone, you'll see the route designation: "PA 318". The use of a specific font from the 1948 era further enhances the historical accuracy of the design.

Meaning and Symbolism

The "PA-318" designation signifies a specific state route within Pennsylvania. The 1948 design is a tangible link to a specific period in the state's transportation history, representing a time when highway signage was being standardized. The keystone shape itself symbolizes the state's central role, the "keystone" in the arch of the United States. Displaying this design is a subtle, yet powerful, expression of pride in Pennsylvania and a love of vintage aesthetics.

Sturdy white ceramic mugs available in 11 oz (β‰ˆ330 ml) and 15 oz (β‰ˆ440 ml), with a glossy finish and comfortable C-handle β€” microwave and dishwasher safe, and made from lead- and BPA-free materials.

These mugs are built from durable white ceramic so colors pop cleanly and prints read with strong contrast. A smooth, glossy glaze gives each mug a lively sheen and makes it easy to wipe clean after daily use.

Both sizes feature a classic C-shaped handle that feels natural in the hand; whether you sip slowly or gulp quickly, the grip is steady. Safety-wise, the ceramic is processed to be lead- and BPA-free β€” suitable for everyday drinking.

  • Material: white ceramic with a glossy glaze for bright, clear prints.
  • Sizes: 11 oz (β‰ˆ330 ml) and 15 oz (β‰ˆ440 ml) to suit small and generous pours.
  • Handle: comfortable C-handle for balanced holding and easy lifting.
  • Safety: lead-free and BPA-free for peace of mind with every cup.
  • Finish: glossy surface that highlights saturated inks and smooth detail.

Perfect for morning coffee, afternoon tea, or a rich hot chocolate β€” these mugs fit comfortably in most cabinets and cupholders. They’re also a reliable choice for office kitchens where items see frequent use.

  1. Everyday use: safe for hot liquids and daily serving; the wider 15 oz option works great for larger morning routines or extra-steamy drinks.
  2. Office-friendly: the classic profile stacks easily with similar mugs and sits securely on standard saucers and trays.
  3. Gift idea: a practical, well-finished mug is useful and simple to display or wrap for gifting.

Quick note: while the mugs are dishwasher-safe, treating them gently helps keep the print looking fresh longer (see Care tab).

These mugs are rated for microwave and dishwasher use, but small habits extend their life. Run them on the top rack of the dishwasher and avoid high-temperature commercial cycles whenever possible.

For longest-lasting print clarity: hand wash with mild dish soap and a soft cloth, avoid abrasive scouring pads, and don’t let them soak in strong detergents. When microwaving, use short intervals and avoid empty heating.

Available sizes: 11 oz (approximately 330 ml) and 15 oz (approximately 440 ml). The 11 oz is a classic coffee size; the 15 oz gives extra room for cream, froth, or larger servings.

Each mug has a standard-width mouth for easy sipping and cleaning; height and diameter vary slightly between sizes to maintain comfortable proportions and sturdy balance.
