Leather treatment on a game used glove?

[CampWest]

If it were me, I'd want the glove exactly as it came off the field. But I'm not heavy into vintage gloves or anything.

Totally agree... problem is leather breaks down over time, if steps are not taken to keep it healthy, it will dry out. Once it dries out, it will crack and split. If it cracks it can never be repaired. I think a very minimal treatment once every few years is necessary to keep it in "just off the field" condition - depending on how and where it is stored. Also, most players use lanolin to treat their gloves so potentially that would be consistent with how the glove would be treated if the player were still in possession of it.

I'd love to know what the HOF or other museum's do for preservation of leather.

here's one search result...

The most common forms of deterioration in leather are due to prolonged dryness, mold, mildew and fungus, U/V light, insects and vermin
