I have an old KODAK film wallet containing 30 negatives all of which
are of a family from the 1920's some are children as flower fairies,
what site would i go to to find out more info and value of this item?

Search eBay and see what it comes up with. For best results, you need
to watch it for a couple of weeks.

For anything that old, it will also be worth contacting Kodak. If
they're well preserved they may be interested in buying it off you.

your looking for
