From the GCAS Library/Archives:
No photos of this particular bowl are known to exist, but the following description may be accurate enough that someone may recognize it if they have seen it. This bowl was reportedly unearthed on private ranch land located east of Silver City, New Mexico, at some time during the late 1970s through the 1980s.
It was described as “…a beautiful Mimbres Classic bowl…[depicting] a Mimbres warrior standing up with a shield on one arm and a three-pronged spear-headed staff in the other…”
The individual who excavated this bowl was not related to the landowners and it appears he did not have the landowners’ permission to remove this artifact. However, it does not appear that the landowners made any report of theft to any law enforcement authorities. Nevertheless it was assumed at the time that the individual who took this bowl eventually sold it to either an intermediary or directly to a private collector.
If anyone encounters a bowl matching this description, either on display or in a photograph, you are welcome to contact the GCAS via this website so at the very least we may be able to alert the individual currently in possession of it.
