Royal Haeger 1998 #4304 floor or table vase

This Haeger vase is 13" high and 8" in diameter at the widest. I'm still kind of loving on Haeger since I waited so long before adding a piece or two to my collection. I haven't found any really unusual pieces, at least nothing I wanted to pay for, yet. This #4304 vase was a staple in the 1980s-1990s and maybe longer. It is a classic style and size. This one is mint and just has so much going on on the bottom that I couldn't resist it and paid $7.50 for it. There are multiple labels, a small section that is glazed on a mostly unglazed base, some printing, some numbers and an "X". Wow. Were they trying to tell us something?
