Over a period of a couple of months, a client of mine was interested in purchasing this photo-realism painting from me through a dealer in London. It was two years prior that we did purchase a signed print by this artist through that same dealer. However, this time, after several weeks of negotiation and consideration, my client declined to proceed with the purchase for a variety of reasons.
When a collector is looking for a particular type of art, he/she needs to be prepared to negotiate. One should always have a plan as to how to proceed. A situation where all the pieces fall into place in a timely fashion is the exception. Have a realistic budget in mind and allow for some "wiggle room."
