Ex. the Mineral Collection of Archduke Stephan Franz Viktor of Hungary (1817 to 1867), with a historic Archduke (Erzherzog) Stephan label incorporating his coat of arms. This label measures 9.9 x 8.2 cm; it is complete (untrimmed) and is numbered 435/14. A small label bearing this same number is glued beneath the specimen plus a Carl Rumpff label, dated 1889. The Archduke label is in very good condition but has been folded twice, leaving one vertical and one horizontal crease. The specimen comes with one of the unique green card boxes which the Archduke had specifically made to house the specimens.
