Wax Lincoln is by Sandy Williams IV, and version that melted in DC
is not the first he made:
The 3,000-pound Lincoln candle — it had 100 wicks meant to be lighted — was installed at the same location in September . Days before it was set to be officially unveiled, someone lighted more than half of the wicks and then left the piece unattended.
...
the artwork, paid for with a mix of private and public funding, cost a total of $150,000, which includes the cost of the replacement statue after the first Lincoln burned.
