The obvious question for museums to ask themselves is: which artworks in our collections passed through these individuals or their businesses and are there any provenance gaps or discrepancies that require further verification.
The number of questions marks "?" (49) and "probably" (41) and "possibly" (30) and "might have" or "may have" (12) suggests the presence of guesswork and speculation.
Below are a few of the artworks known to have passed through Heinemann or Mont.
