PA-320 1948 Coffee Mug: Design Overview

This coffee mug showcases a classic design inspired by the 1948 Pennsylvania road sign for Route 320. The artwork pays homage to a significant era in Pennsylvania's highway history, reflecting a time when the state adopted a standardized and more legible approach to route markers.

The Keystone Symbol

The central element of the design is the iconic keystone shape, a prominent symbol of Pennsylvania. The keystone represents the state's historical significance and its place as a "keystone" state in the Union. The white background of the keystone sets the stage for the bold black numerals of the route number.

Vintage Route Marker Aesthetic

The "320" within the keystone, rendered in a vintage font style, specifically references Pennsylvania Route 320. The style evokes the design standards adopted in 1948, marking a transition in signage design towards greater standardization and readability. The simple color scheme of black on white is typical of that period.

A Nod to History

This design is more than just a road sign; it’s a representation of a period in transportation history. The 1948 design is a nod to the past, reminding us of the evolving nature of road signage and the ways in which states established their unique visual identities.

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.

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.
