Bruce MacPhersonAs Peter said, the Thorpe is very difficult. I have not seen any for individual cards for sale in the last few years. The Sisler can be found occasionally.
The Collins McCarthy Hornsby is from a set that is more difficult than it is given credit for. Since I believe the card is considered to be Hornsby's rookie card it may be tough to find. A Boston Store card (parallel set) may be easier, but still difficult.
The E90-1 Jackson can be found as there seems to be one in every other major auction. But the value is creeping up towards 10K for even the lowest grades.
I have no idea about Yuenglings.
