After recently buying the mammoth Complete Far Side collection (among the best $81 I've ever spent), I've decided to catch up on my other favorite comic strip from the late-80s/early-90s, Calvin & Hobbes. The only books I still own are the Tenth Anniversary and Attack of the Deranged Killer Monster Snow Goons (or some such title). I know that the last 4-5 years (starting with Snow Goons) are only available in seperate, single editions, while the first 6 years were available individually and in a trio of Treasury editions (Essential, Indispesible, and Authorative). I've heard conflicting reports about the completeness of the Treasuries, some saying they include everything from the first six sets, others saying that they used only selected strips, with the real incentives being colorized Sunday strips, a small (though exclusive) cartoon, and a cheaper per-comic price. So basically, my question is, do I have to buy each of the first six single sets to get all of the early syndicated strips, or will the Treasury sets cover the first six years completely? Thanks. Evan P.S. Is there anything special about the two Sunday collections (Lazy Sunday and Sunday Strips 1985-1995) that would make them required purhases?
