Should I get an appraisal? Where?

Appraisals can be quite subjective and vary extremely. Reliability improves with the expertise of the appraiser, the comparison of the artwork to known sales (a known artist in a recognized style and period are easiest to appraise), and the independence of the appraisal from any imminent buy/sell transaction.
