These are stamps that can be customized to bear an image from a personal photo or design that is submitted by the purchaser of the stamp and then applied either to a blank area on the stamp or to a label attached to the stamp. On Colnect “Personalized – Official” means stamps that use the format frame for personalized stamps produced by a country, but the design is commissioned by the national post office and the stamps are sold by the Post Office to the general public just as they sell regular commemorative stamps. On Colnect “Personalized – Private” means stamps that use the format frame for personalized stamps produced by a country, but the design is commissioned by a private individual and the post office only sells them to that private individual who contracted their design, and not to the public at large.
