Cloetta Chocolate

Cloetta was established in 1862 in Copenhagen by the three Swiss brothers Bernhard, Christopher and Nutin Cloetta. The movement expanded and in 1873 a factory was built in Malmö. This factory was moved in 1901 to Ljungsbro. The Cloetta family sold the business in 1917 to the Swedish Chocolate Factory AB with Svenfelt family as majority owner. There's the nutshell history. So, the question is this, how old is this paper, ad, bookmark thing I found in one of my books? 
                                                                                                    

I am going to guess the 1920's to 40's. Mostly based on my absolute love for that time period, and this girls hair and clothing. The card says Gourmet Bitter chocolate for connoisseurs, new healthy and tasty, among other things. I believe this particular box of chocolates might be dark chocolate covered gooseberries. Sounds good, cannot say I have ever had a gooseberry. Bucket list add right there. 

This card is in Swedish, which is really cool because my grandfather was 100% Swedish. 100% anything is kind of rare anymore. Perhaps I should have a chocolate covered gooseberry actually IN Sweden?! Madness or brilliance, I can't decide. But either way, Sweden is definitely on the bucket list. The bucket list currently has things scratched out and completed, and there are always new things going onto it. Just as bucket lists should be. And no, I am not old nor do I have a fatal disease, but waiting to start knocking out a bucket list makes no sense to me at all. Insert sappy, cliche sayings about living life to the fullest, don't wait til tomorrow, etc. here. They do have a point though.
