Don; Regarding your question why an image was included in the 1999 PR catalog but not in the 2005 version ...; Back in '99, most of the images were paste-up color copies of chips, not scans. Some of the photo copies were provided to me by other collectors of PR material.

In the later editions of my Puerto Rico catalogs, I scanned virtually every PR chip in my personal collection to improve the quality of images in my catalog. I did not have the ANA-100e chip to scan which is why it got omitted in 2005.
