Martin Eisler & Carlo Hauner Bookshelf in Caviúna wood, Forma S.A., Brazilian

An early and architecturally disciplined example of Brazilian modernism by Martin Eisler and Carlo Hauner for Forma S.A., executed in solid caviúna with caviúna veneer. Designed circa 1950, this compact bookcase embodies the structural clarity and sculptural restraint that defined the duo’s most important collaborations.

The case is constructed in richly figured caviúna, its deep, almost liquid tonality revealing dramatic grain movement across the sides and interior. The satin-matte finish amplifies the wood’s natural depth, creating a layered visual field that shifts subtly with light. Two internal shelves provide balanced storage, while the proportions— 37" high, 39" wide, and 9" deep—offer a refined architectural footprint ideal for intimate spaces.

Most iconic are the carved “gravatinha” legs—Carlo Hauner’s signature bow-tie form—cut with precision and lift. These sculptural supports elevate the cabinet both physically and conceptually, introducing a moment of tension and elegance beneath an otherwise rectilinear volume. The joinery throughout is executed at the highest level: tight seams, seamless veneer alignment, and disciplined edge detailing underscore the workshop standards of Forma S.A. during its most influential period.

At once functional and expressive, this piece operates as refined storage, a sculptural object, and a conversation anchor. It reads effortlessly in residential interiors, galleries, and executive environments alike—an understated yet unmistakable statement of early Brazilian modern design.

A rare opportunity to acquire a foundational work by Eisler & Hauner, where proportion, material integrity, and structural intelligence converge.
