[2] After a lengthy art career that included hundreds of works, 13 solo exhibitions, dozens of gallery showings and countless lectures, Coreen Mary Spellman died on October 15, 1978, in Denton, Texas at 73 years old.

Her longest held position was as an associate professor of art at her undergraduate alma mater in Denton, where she began teaching in 1929 and would ultimately retire from in 1974.

The other founders included Lucile Land Lacy, Stella LaMond, Mary Lightfoot, Verda Ligon, Blanche McVeigh, and Lura Ann Taylor, and the group had an additional 23 active participants.

In August 1990, the Meadows Museum at Southern Methodist University mounted an exhibit titled "The Texas Printmakers: 1940-1965" that included several works by Spellman.

[11] In October 2022, Spellman was featured in an exhibit mounted by the Greater Denton Arts Council on the Forgotten Nine, a group of women artists working at the same time as the Dallas Nine but less celebrated due to their gender.

[14] Coreen Spellman's artistic work was heavily influenced by industrial landscapes, human-made structures, and her Texas surroundings.

[18] The most prominent items of the collection include the 1936 oil painting Road Signs[19] and the 1942 etching Orizaba Market[20] which can typically be found on display within the museum.
