I have a client that is closing his office and had a couple dozen nicely framed museum posters, he wants to donate them to charitable cause and be able to collect a tax write off. Locally our library has a art/poster lending program, the PTO shop, and local recycle shop would all accept the frames and give him a blank form to fill out for his taxes. My question is what kind of value would be acceptable? To frame them today he would be looking at around $150 to $250.
