A lovely Orange Free State Telegraph Stamp.  This is an SG T10 Block of 4, the Een Shilling on the 7 Shilling Violet (F-11), and it is in Fine to Very Fine Used Condition with a pen cancel.  The interesting thing about this one is that it has a single thick line through the value on the top left, and a double line that is thick and thin through the other 3 stamps.  It also has an Overprinted "TF Een Shilling."  This is rarely seen and is valued at L18 in the Stanley Gibbons Catalog.

This item is over $100 USD so it will be shipped in the US using priority mail and overseas using registered mail, to ensure that it arrives in a safe and timely manner.
