Libay was a master of the Biedermeier style. He focused on clarity and precise detail. His work documented his extensive travels through Egypt and Italy alongside Alpine regions. He produced lithographs that captured architecture and natural features with technical accuracy. He avoided dramatic romanticism. Instead, he preferred a clean, descriptive approach that recorded the world as he saw it. This method made his work popular among scientists and explorers.

Modern collectors value Libay for his ability to document historical sites before the era of mass photography. His prints of Cairo and the Nile are particularly sought after for their architectural honesty. These works record nineteenth-century travel. The muted colour palettes and sharp lines of his lithographs suit contemporary interiors. They offer a sense of historical perspective without the clutter of ornate Victorian styles. His art remains a staple for those interested in the intersection of geography and art.
