25TH ANNIVERSARY TSR
TSR Silver Anniversary | Series | RPGGeek
The TSR Silver Anniversary logo was printed on most of the D&D products WotC released during 1999. Some of these releases, such as the "Return to.." sequel adventures and the Silver Anniversary boxed set, were written specifically to celebrate the 25th anniversary of TSR. Other products carried this logo simply because of the year they were released.
Silver Anniversary Collector's Edition - Acaeum
As a celebration of the 25th anniversary of Tactical Studies Rules (1974-1999), TSR released a "collector's set" of some of the most popular and best-selling D&D material. Only 5,000 copies of this set were printed, and first offered at the 1999 GenCon convention (where many were sold, for $59 retail).
