I found the Hauls of Shame Barry Halper top 100 list jaw dropping.
http://haulsofshame.com/blog/?p=1465
The list includes items stolen from the HOF, NYPL, & BPL.
Thus far, the thief seems to skate free while so many others lose including the donor, the HOF/Library, the auction house that may have unkowningly sold the item (bad press), and last, but not least, the collectors who spend significant money to grow their collection only to learn the item may be stolen property. The HOF's position on the thefts makes me feel less sorry for them and more compassionate for those who donated in trust that the cards & memorabilia would be well cared for.
A truely sad state of affairs.
