I had a chance to examine the document below in Eric Jackson's inventory last month at CHICAGOPEX. Sadly, way beyond my means. Sorry, no high-resolution image available.
The total Scott Catalog value of the stamps is $4,713.50.
Scott RK7, RK13 and RK4
two vertical pairs and a single of the $10, two vertical pair, one horizontal pair (s/e) and two singles of the $5, and a vertical pair with partial plate number of the $2, all tied on the back page from a document. Paris, France.
