I'm so glad this little card made it back to it's family.
I have no idea why I figured it was from the 30's, maybe the font? Maybe it could be earlier since the card doesn't say "and family" or list children. Maybe it's not that old and the children have already grown, so that's why the children aren't listed. It adds some mystery to the card and it will be interesting if you can narrow down the time frame.
I was curious as to how it got all the way to Winnemuca, NV in a misc box of post cards and photos? The post cards I bought out of that bunch were all from the midwest.
Anyway....glad I could be of help!
