Original 1st printing 12&1/8 x 19&1/2" concert/event poster for the Powder Ridge Festival, a three-day event held at the Powder Ridge Ski Area in Middlefield, CT from 7/31-8/2/1970 (*event was canceled after the crowd had already shown up- more on that below)

Design by Sicilia/Lassen, poster lists appearances by Sly & the Family Stone, Eric Burdon & War, Delaney & Bonnie and Friends, Fleetwood Mac, Melanie (*the only act who actually performed), Mountain, J.F. Murphy and Free Flowing Salt, Allan Nichols and James Taylor (7/31), Joe Cocker, the Allman Brothers Band, Cactus, Little Richard, Van Morrison, Rhinoceros, Ten Wheel Drive, Jethro Tull, Tony Williams Lifetime and Zephyr (8/1) and Janis Joplin, Chuck Berry, Bloodrock, Savoy Brown, John B. Sebastian, Grand Funk Railroad, Spirit, Ten Years After and Richie Havens (8/2).

 Extra-thin flat index stock poster is in good/decent (B to B/B-) condition; there is a moderate amount of edge/corner wear (tiny tears, nicks, creases, etc.), along with a series of fairly well-camouflaged staple holes, a small stain in the lower right margin, a 1" tear (sealed on the reverse with clear tape) in the top center margin, a few stray tiny pin-prick surface smudges/stress creases, a small "worm hole" just underneath "Free Camping" and a bit of mounting residue on the reverse (item was originally mounted to foamcore and professionally removed- no other restoration was performed)... definitely a bit on the used side, but still a very presentable example.

 Conditional issues aside, it is still a fascinating artifact from what (by virtually all accounts) turned into an unmitigated disaster. Read all about what happened when tens of thousands of people (with a lot of drugs) showed up to a festival that had been called off only after the entire crowd was on site;
