Looking for advice
My Dad has an extensive collection ... several thousand, probably, most sorted into albums according to theme. There's military, European countries, railroad, humor, and more. I recently spot-checked a European album and found some from 1902. There are also lots of modern/contemporary. He's now in memory care and we're starting to think about disposing of his collection, especially if there's any money in it that could help support his care. Not interested in doing individual listings on Ebay etc. Where do we start?
