I took pictures of this phone in Mexico City while visiting the house of Diego Rivera and Frieda Kahlo. While I was looking for further reference images, I found that its likely a L.M. DE100 wall phone 1921-model. Riveras phone seems to be missing the mouthpiece (which I added) and I couldn't pinpoint the exact font of the digits . Putting the model on sketchfab (in an acceptable texture-version) was an adventure in itself.
It says that I can't use it for commercial purposes. Does that mean I can't include it in my film if I want to make a commercial film?
When we were trying to retain customers solely through email, we noticed that our open rates were dropping. We decided to try other channels and chose viber text messaging. I was hesitant at first, but it turned out that people respond more readily to short messages in Messenger than to long emails. I found detailed information and a convenient tool for working with Viber on bsg.world. Now we combine our email campaigns and get much more responses.
Great work -- I love the attention to detail.
