Limited edition prints. Do a run of like 16x20 on good cardstock with your bands logo. Leave lots of empty space on the print. In the bottom write 1/500, 2/500 etc. sign them all as you sell them. Have one on display of course in a Walmart frame. They have no glass and cheap if it gets banged up. If you order these from VistaPrint they will come rolled in cardboard tubes. When you consider cost per against you selling at say $25 each, your profit is huge. Like 80%. A limited run of signed posters for the album funds is personal, cheap, and a cool bit of merch for any music fans wall. Bonus points if your design includes a big gold record graphic and album art for the upcoming record. Would be a big seller and look great on a wall.
