Another Sculpture in the City by Robert Indiana.
(I seem to keep taking pictures of his work from the wrong side.)

ONE THROUGH ZERO (THE TEN NUMBERS)
ROBERT INDIANA (B.1928-)

The NUMBERS sculptures are a monumental example of Robert Indiana's
long-held fascination with the power of numbers, a subject
which stands as one of his most important iconographic themes.
Every number from one to ten has a specific personal resonance
for Indiana, relating either to events in his own life (such as highway routes
and buildings where he lived), or to the cycle of life itself.

For Indiana, the number one represents birth, with the numbers
ascending through adolescence to maturity, ending with the number zero,
which stands for death. NUMBERS has a monumental solidity
that underlines the way the sculptures stand as a  poetic condensation
in Indiana's multifaceted engagement with the symbolic, allegorical
and formal aspects of numbers.
