Sello blanco en barajas de USPC

[rave]

Dando una vuelta "por el internet" me he encontrado un par de barajas con este sello, ¿alguien sabe algo? En las típicas listas de sellos no aparece.

Os adjunto fotos de otra baraja con sello blanco

Ni idea, la verdad.. Tengo algunas barjas Hoyle con sellos así alargados parecidos (más pequeños)....

Creo recordar un sitio que hablaban de eso.. A ver si lo encuentro y te digo..

Pues ya encontré la solución:

For some time, there also was a stamp for tax-free playing cards. To the left is a stamp that was in use by the U.S. military c. 1946. Below are two examples of USPC playing card decks provided to the U.S. Government for military use in the mid-fifties. In the center is an enlargement of the tax-free stamp (all three images courtesy of Lee Asher from his informative article “The White Label” in Issue No. 13 of CARD CULTURE). Lee has since sent me some additional images of two League back Bicycle decks from his collection that also feature the white tax-free stamp, below.

For another interesting example of the use of a tax free stamp, see the Rider Back page, which includes a picture of a deck exported to Cuba.
