Appreciation post: the old guy at the Mesa library sale who told me my stamp albums were ruining my stamps
He watched me load 3 albums into a tote and said 'you just wrecked the gum on every mint sheet in there, kid' and then showed me his 40 year old stockbook where the stamps still had full gum. Do you use stockbooks or albums, and did anyone else learn this the hard way at a sale?
