If You See Sid Tell Him...

Part of a magazine advertisement from October 1986.

Another advertisement - this time from November.

Who was this mysterious "Sid" in the British Gas shares ads? I found myself wondering if it might be the hissing Sid of Captain Beaky fame, you know, the snake whose innocence we'd all been proclaiming back in 1980?

But nobody I mentioned my theory to thought it very likely.

More of the November 1986 magazine ad. 

To help as many people as possible afford to apply for British Gas shares, we're making the minimum investment level as low as possible. And payment will be in instalments... 

Did you get a "share of the shares"?
