What do Bush Stadium, Indianapolis Public School 97, the Syracuse Depot, Wollenmann House in Ferdinand and the Colgate-Palmolive plant and clock in Clarksville have in common? In case you haven’t guessed, they represent five of the 10 most endangered places in the state, as identified by Historic Landmarks Foundation of Indiana. Their very existence, not to mention their original habitat, is in peril, and artists have come together to make art on their behalf.

Rather than your more typical art-as-donation-to-a-cause approach, the artists participating in R-Value: Revive, Restore, Reuse have made art specifically inspired by these buildings and places, which could be construed as a more subtle form of protest art. As is to be expected, each artist interprets her or his subject uniquely, from the straightforward rendering in Karen Woods’ “Twin Bays” of the Twin Bays building in Lawrenceburg (a c. 1860 Italianate building on a 20-acre lot overlooking the Ohio River, threatened by sprawl) to Ellen Nylen’s conceptual “Old Skool,” a dressmaker’s dummy adorned in a recycled paper dress and a belt of small pencils, giving new meaning to the phrase “pencil thin.”

Always good for a visual pun, Kyle Ragsdale (who is also Harrison Gallery curator) offers “Protectors of Eville” in support of Washington Avenue Historic District in Evansville. The painting is quintessential Ragsdale, with elongated figures dissipating from a dark backdrop — in this case on horseback, lances in hand.

Elizabeth Sparrow Boring’s “Shoefitti at the School,” which features two child-sized shoes covered in tiny toy soldiers and heavily coated in white paint, calls to mind shoes strung over telephone wires. This three-dimensional offering intends to bring attention to Old Lowell Grade School, in Lowell, which is on the verge of collapse.

While many other works are notable as well, this is not a large show by most group-show standards. But then again, it is limited by the constraints of its subject: Ten buildings have generated slightly more than 10 works of art, and the artists certainly deserve recognition for a worthy effort. This isn’t edgy art along the lines of typical protest art — but one hopes it will make a difference.

Oh, in case you were wondering, the other five endangered places are Maple Grove Historic District in Bloomington, Twin Bays in Lawrenceburg, Old Lowell Grade School in Lowell, Jennings Building in New Castle and Washington Avenue Historic District, Evansville.

A complete list of contributing artists includes Elizabeth Sparrow Boring, Jason Dorsey, Beth Eisinger, David Finegan, Tyler Meuninck, Kipp Normand, Ellen Nylen, Artur Silva and Karen Woods.
