RIPTA wants bus riders to get in touch with their creative muse.

To commemorate its 50th anniversary, the Rhode Island Public Transit Authority is calling for artists to send their “vibrant, eye-catching, unique designs,” to create a bus pass, a news release said.

“Creating a design contest for a commemorative pass is a great chance to engage local artists and give them the opportunity to showcase their skills and creativity,” said Barbara Polichetti, director of public affairs for RIPTA.

RIPTA came to be in the 1960s, but before that there were steam locomotives, horse car railroad and en electric trolley in Newport, the release said.

There are several prizes for the winner: A $25 gift card to Thirsty Beaver (Smithfield & Cranston), a Pizza Bowl certificate for six people at Lang’s Bowlarama ($75 value) and a Providence Bruins prize pack which includes four game tickets, a signed hat and hockey stick and more.

Participants have until March 4 to submit their designs to marketing@RIPTA.com. All rules and requirements can be found at RIPTA.com.
