Over the last six years I have received a great many e-mails with some very challenging questions which I haven't been able to answer. As a result, I would like to take advantage of the medium of the Internet and use this page as a online forum for visitors to exchange questions and any puzzling Van Gogh "imponderables". Perhaps someone in Munich has a question about one of Van Gogh's works that someone else in Tokyo just happens to know the answer to.
Send your questions to me, I'll post them (with your e-mail address, if you wish) and with any luck we can solve some of these mysteries by working together.
Click on any of the categories shown below and you'll find a few of the imponderables I've received so far below. These should serve both to give a flavour of the types of questions which would be ideal in this forum, and because I genuinely don't know the answers to the questions and would love to hear from someone that may be able to give me some information.
Again, I'll be very happy to post any further challenging questions if you'd care to pass them along to me at email@example.com.
