I have a version of this too. My daughter's high school orchestra was having a fund-raiser. The kids played music and during the breaks there was a split-the-pot, silent auctions, etc. My daughter suggested I do a "homebrew basket" for the event. Beer, glassware, some pretzels, a schmancy bottle opener, etc. I said, "You better check with your orchestra teacher... the school is no place for beer" and she got back to me a couple days later and said the teacher was cool with it. We agreed to take a picture of the "prize" (which was a case of beer, four sixes of different styles, two etched glasses with my logo on it, a big barrel of pretzels, an opener all in a wooden case I made) and put the pic at the auction table and keep the beer in my car. Whoever won it would take delivery of it outside the school. Probably not kosher but we did it anyway.
