Fair, here is how Shannon Applecline describes the situation on the DMsGuild labe:Just being pedantic here (because that's how my brain works), but the Forgotten Realms Adventure book wasn't a hybrid, it was fully 2e. You may be thinking of the Greyhawk Adventures book which had 1e trade dress but purported to be compatible with both editions on the cover. Inconsequential, I know.
"A Series of Setting Books. While AD&D was transitioning from 1st edition to 2nd edition, TSR changed over from publishing hardcover rule supplements to publishing hardcover setting supplements - probably in the hope that they'd sell well despite the transition. Forgotten Realms Adventures was the third, following Dragonlance Adventures (1987) and Greyhawk Adventures (1988) - or perhaps the fourth if you count Manual of the Planes (1987)."
"Amusingly, Dragonlance Adventures was pure 1st edition, Greyhawk Adventures was advertising as being compatible with both 1st and 2nd edition - which in truth meant it wasn't perfectly aligned with either - while Forgotten Realms Adventures was pure 2nd edition. Together, the three books offered a perfectly symmetrical history of AD&D's edition change."
