The members of Umphreys McGee will sign a series of posters that will be auctioned on-line to benefit the Eddie Hrebic Family Fund. Hrebic, a friend of the group, died recently of a sudden pulmonary embolism, leaving a wife Melanie and four month old son. These five concert posters, designed by Jeff Wood of Drowning Creek Studios, will be auctioned simultaneously over ten days via eBay beginning Monday, July 18.
