Interstate 73 - Black Mug Design

This design sets the route number 73 inside the shield-shaped marker that has signalled American interstate highways since the system was built.

Visual Elements & Composition

The numeral 73 is the centre of the composition and the only thing the eye needs to read. Its bold, blocky letterforms sit within the outline of the classic route shield, with the shape's upper curve and tapered base framing the number. Nothing is added around it. The layout is flat and symmetrical, with no decoration, which is why it reads at a glance like a sign seen from the roadside.

Meaning & Symbolism

The shield and its numbering are the visual language of the Interstate Highway System, created by the federal government in 1956 to connect the country with a single network of routes. Each marker tells a driver which road they are on, so a route number becomes a small act of navigation. Interstate 73 carries that tradition into a single number, honouring the road network and the ordinary public signage that guides people across the country. For anyone who loves Americana, transportation, or geography, the design turns a familiar roadside sight into something to keep on the desk.

Crafted for the Morning Commute on Your Desk

A mug is turned slowly in the hand, so the shield comes into view one side at a time. The marker's clean outline suits that rotation: the number is always visible, and the shape holds its identity whether you are looking at the front or following the curve around to the handle. It is the kind of road sign you notice on a long drive, now waiting beside your first cup of coffee.

Glossy black ceramic mugs in two practical sizes — 11 oz (≈330 ml) and 15 oz (≈440 ml). Comfortable C-handle, microwave- and dishwasher-safe, and manufactured to be lead- and BPA-free. Note: printed blacks may read slightly different from the mug’s base color.

These mugs are made from solid ceramic with a glossy glaze that gives a deep, even surface for printing. Sublimation printing embeds ink into the glaze so artwork sits smoothly on the mug rather than simply sitting on top — that means better resistance to fading and scratching during normal use.

They’re available in the classic 11-ounce size for everyday black coffee and tea, and a larger 15-ounce cup if you like extra room for milk, foam or a long pour. The C-shaped handle is wide enough for a secure grip and balances the mug well when full.

  • Material: 100% ceramic with a high-gloss finish for punchy, saturated results.
  • Sizes: 11 oz (≈330 ml) and 15 oz (≈440 ml) — choose your routine size.
  • Printing: sublimation process fuses color into the glaze for durable imagery.
  • Safety: lead- and BPA-free; meets common food-contact safety standards.
  • Design note: very dark artwork and the mug’s black base can produce subtle shade differences — add a thin lighter outline to ensure contrast if needed.

These mugs are at home in the kitchen, on the office desk, or tucked into a morning routine. They work for espresso shots, pour-overs, oat-milk lattes — you name it. The larger size is handy when you want a second cup’s worth without a refill.

  1. Daily use: fill with your preferred brew and sip — the mug handles hot liquids safely.
  2. Office-friendly: fits most standard mug warmers and sits securely on communal trays and kitchen counters.
  3. Gifting: packs well (wrap with a soft layer) and pairs nicely with coffee beans, tea tins, or a small box of biscuits.

Practical tip: for very dark designs, try a thin light border or a small margin so the artwork reads cleanly against the black ceramic.

These mugs are both microwave- and dishwasher-safe, but gentle habits extend the life of the print. We recommend dishwasher use on the top rack and milder cycles when possible.

Hand-washing is the friendliest option: warm water, mild dish soap, and a soft sponge. Avoid steel wool, harsh scouring pads, or blasting with extremely hot industrial cycles. And a quick reminder — don’t microwave an empty mug.

Two sizes: 11 oz (approx. 330 ml) and 15 oz (approx. 440 ml). The smaller cup is the familiar, everyday size; the larger one is for fuller pours and extra-creamy drinks.

Each mug’s mouth and height are proportioned so they’re easy to drink from and easy to clean. If you’re pairing with saucers or nesting in cabinets, expect the 15 oz to be slightly wider and taller than the 11 oz.
