Constant in front of 'Ode à l'Odéon' or unknown work

1970, circa

It's hard to match the wok in the photo to an exact work. In 1970 Ode à l'Odéon was already finished and looks vastly different than the work in the photo. If the work is indeed Ode à l'Odéon, then it's most likely an earlier version. In that case the photo is more likely taken at an earlier date. If the work in the photo is not Ode à l'Odéon then the work has yet to be identified.
