Possibly in direct conflict with the technology-laden posts I normally tend to have... This wedding invitation also contains a paper record player!
Yes its wildly inefficient, yes its a DEAD technology, yes its probably 28 times the effort per invite than a wedding invite should be but- I love stuff like this.
