1kr gray lilac newspaper stamp is a notable stamp issued by Austria Post in 1861. However, not the single item but their multiple is considered to be more attractive in the philatelic circle. One of such items is a block of thirty 1kr gray lilac newspaper stamps. In an extremely fine condition, this unique lot was auctioned for $29,000 by Robert A Siegel in May, 2001. This is the largest recorded multiple of the Austria one-kreuzer 1861 newspaper stamps that was one of the highlights of the baron Alfonse Rothschild auction and is considered to be a rarity of the highest order.
