Olive green mouth-blown crackled glass

Set of 4 stemmed glasses, made individually, each glass is unique, its size and weight vary depending on the glass. They weigh between 430 and 460 gr. Olive green in color, they are very original with on the one hand the cracked glass and on the other hand the addition of relief patterns. They date from the 60s/70s and I think come from the south of France because we lived there for a long time, but unfortunately I can't be more precise.
