The collection of Löffler’s figurative sculptures covers the period from 1940s until the very end of his career, tracing the gradual development of his art and vision. Throughout his creative life, the materials he preferred were stone, Bronze and exotic wood.

A theme prevalent in his works, however, is that of a woman, interpreting various moments from her life. Formally, Löffler’s sculptures always favour precise craftsmanship and regard the beauty of the material itself. Löffler’s smaller sculptures and compositions, often made of precious materials such as ivory, coral, amber or silver, are equally interesting and masterfully executed.
