There is not enough evidence to prove that these are from the same artist. When I was adding both of these artworks back in March this year, I also noticed the similarity in name too.
Delise Freeman: (Delise Freeman – Southern Tablelands Arts) and Deadly Del Designs
Denise Freeman: From UoW Academic Paper ReDreaming Dharawal (table excerpt below)
Due to the significant time difference between creation, there is a slight possibility that they may be the same artist. Given the obscurity of artwork documentation prior to the digital age and the fact that they’re both from reputable sources (Delise has her own arts business with her own namesake, and the UoW paper mentions Denise twice, as well as in an Aboriginal arts database), I’ve determined that they’re not the same artist.
Appreciate your understanding. I merged Be Free Art with Be Free yesterday evening as the entry was from a previous Sydney hunter, but forgot to advise here.
