I have spent the last two mornings at my local library looking at old news paper advertisement from local jewelers, (1878 - 1924) I found plenty of ads, but not about the jeweler I was looking for.
Anyway, here are two that I thought were amusing.
This one is a give-away!

I guess this one is when the major manufacturers were tring to compete with the dollar watches.

For those that are interested here are a few more.
If they only had credit cards

I noticed when one jeweler changed their ads the others followed.
