my preference would be for little knick-knacks that they know the fan-base collectors would love to own, but that not big enough for a mass appeal sale.
For instance, just since 2020, I would have been delighted with even just 7inch vinyl- with a single track on each side. Much like the recent Atomic City 7inch.
