Call your mum! poster

A poster of reminder in this crazy Covid-19 times.
These telephones were in every household in Yugoslavia during 70' & 80's. I remember using one in my nan's house when I was a kid during the early 90's.
They were produced by a slovenian company Iskra. Their telephones were state of art of the time and you can still find them today, in more "modern" 90's version, around ex-yu countries' households and offices.
