Hi Toni,

Thank you for contacting Mearto with your appraisal inquiry.
The Perry Como provenance is fun but unless you can prove it, it doesn't really add much value to the bowl. From what I can make of the signature, it doesn't look like the names of any of the famous makers whose works bring substantially more so for the purposes of this appraisal, is negligible.
Based on the photos and information provided, and subject to examination, this is:
