I recently acquired this Sterling silver souvenir spoon, hand-engraved with 'Covina CAL' on the bowl. I'm told it dates to the 1910s.
If it is from that period, it might very well have been bought at The Peoples Store on Citrus. This is exactly the kind of knickknack they sold. Clapp's Pharmacy is another possibility. Both carried souvenirs and curios in addition to their regular goods.
"The Peoples Store" can be seen over at the far left edge.
I was really happy to find the spoon. I saw one just like it 10+ years ago but failed to score it. I think my Covina antique collection is complete now. This was kind of the Holy Grail for me.
