In 1913 Keck designed a memorial plaque that was cast from metal that had been salvaged from the USS Maine after it was raised in Havana harbor the previous year. Over a thousand of the plaques were cast and they are spread unevenly all over the United States. In 1931, Keck completed the Great Seals of the Commonwealth of Virginia which had been commissioned by the Commonwealth. The obverse of the seal is still used to this day and appears on the state flag.
