Notes:
1st Aladdin books ed. Locus1 is the source of most data, but wrongly reports hardcover format.

WorldCat (OCLC, below) reports "Aladdin Books : Maxwell Macmillan International, New York, 1991".

This is a Robert Maxwell-era "Aladdin Books / Macmillan" publication (1991 to 1994?). Probably its title leaf in relevant respects, and cover design including Canada price $4.95, match the 1992 Aladdin Books that may be viewed at Open Library or Archive.org (see 1992, On All Hallows' Eve or Borgel).
