Dear friends,
a few days ago I received a letter from Joe Offer urging me to ask my question to all of you.

I am seeking the following video archive for scientific purposes: https://folktrax-archive.org/menus/cassprogs/3300iinterfolk.htm

I study the life and work of Bulgarian ethnochoreologist Raina Katsarova. A group of Bulgaria, as well as Raina Katsarova took part in the International Festival held in London in 1931. I very much hope that I can see this record and have some footage with the group from Bulgaria.

Thanks for all the help
nice and smiley day
Ivaylo Parvanov
