There is nostalgia and nostalgia. These gollywogs are in the current Oxendale's supplementary Christmas catalogue. They are called "nostalgic characters".
In my day lots of children had them. Apart from buying them in the shops, your mammy or granny would knit or crochet one for you.
For us as children there were no racial overtones to them. They were to us what Kermit the Frog was to a later generation.
Mind you, these days people can be barred from tv shows for even using the word "gollywog" in the Green Room.
I do remember that, as early as 1968, some of my American fellow students were appalled at the Lyons Tea Minstrels ad in a Bruges cinema. I frankly didn't know what they were on about.
However, you live and learn and I must say I am surprised to find the gollywogs turning up in a modern catalogue regardless of how they are described. It's one thing to refer to them in a historical context, as I am doing here. It's another thing entirely to start flogging them in a Christmas catalogue.
I wonder if Oxendales will get any adverse reactions?
[Update: the site now says the item is no longer available, but does not specify whether it was withdrawn or stocks ran out due to overwhelming demand. Given that the images are still there, it must surely be the latter. Well I'm blowed.]
(Thanks to Nora for pointing out the catalogue item.)
