Wrong, I was a big stamp collector until the 1980s. I loved the engraved stamps for their artistic merit. Now, especially U.S. stamps, are photographs with self-adhesive backs, printed with a row of plate numbers which make buying sheets rather than blocks of old, collectables. A sheet often has four or more pictures on it rather than a continuous loop of engravings. I don't want to be a sheet collector and don't value the mere photo stamps versus the personally engraved stamps.
