just saw this video demonstrating the sounds of our loved analog four. i want to have such a vinyl card! does anyone know where i can get it??
thx. and push things forward
havent ever seen that, or something similar !
i guess you could cut out a slice from a record and glue it to a post card 
Back in the days, flexi-discs were quite common. They used to come with magazines, comics etc… you can’t play them very often, as they tend to wear out soon. So the usual process was to transfer them to cassette tape as soon as possible when you wanted to listen to the contents of it more often. Right now, there are some manufacturers who offer such postcard-flexis for the nostalgic people, e.g. one of them can be found here:

As for the A4 card I assume it was a promotional item in small quantities by Elektron and not up for sale, but you could always ask Elektron directly.
+1 thx. i will do…would be nice to scratch some analog 4 sounds. sampled by octa an the merge it with the analog 4…full cycle fo my love. turntable, sampler, synth…hehe
