Note: From #17 on, all titles were part of "The Johto Journeys", which can be viewed as a sub-series of this one. From #20 on, this phrase appears to have always been included on the cover. However: Every cover we have seen of #17 includes this phrase; no cover of #19 we have seen does; and covers appear both with and without this for #18. The reprint series published in 2018 changed the series numbering.
