I recently came across these and found out what they were after asking around and doing some research.. This is an authentic 2 reel to reel promo by London Wavelength called "A Portrait of Queen ". This 2 part - 2 reel radio show aired in 2 consecutive weeks in 1978 - July 9th and July 16th. This show consists of Tom Browne interviewing each of the band members including Freddie Mercury and playing songs from the Queen catalog up to the year 1978.
There are not a lot of these around to my understanding I believe there were 5 of these promos but mine like I said before is Unplayed.
Shoot me an offer! Thanks!
