Kellogg's Sugar Smacks "Star Trek Klingon Invasion" Transfers Offer

"Star Trek Mission 271" — "Space Energy Comes From Sugar Smacks"

A very straightforward cereal promotion, featuring six different sheets of transfers. The advert implies there was only one "Background Scene", at least if we assume that the one shown in the advert is actually just a variant of the one printed on the packet backs; the ad shows a desert planet with a canyon, but all the packets we've seen show an ice planet with caverns. The sky is the same for both. There were two packet sizes (by weight), so logically one might expect two different scenes, & normally reliable sources insist both existed — but I've yet to see hard evidence. However, I'm always happy to see hard evidence, so bring it on!


The front of the Sugar Smacks packet featured the same design of "Mr. Spock" for quite a long time, through several different promotions, with just the panel at the bottom right of the packets adapting to illustrate the change from one to the next.

The previous Sugar Smacks Star Trek promotion, for five Star Trek badges, was being advertised towards the end of the previous year — for example, in a full-page colour ad on the back cover of "Smash!" for 27th September 1969. (Co-incidentally, the previous week's back page ad was for Letraset Action Transfers!)

It looks as if this "Klingon Invasion" promotion didn't last very long.

The ads ran in a few comics on the 13th & 20th February 1971; after extensive searching of over two dozen different comics titles, we could only find it in these issues:

Sally, 13th February 1971 (full back page, in colour)

Buster, 13th February 1971 (full back page, in colour)

Tiger & Jag, 13th February 1971 (full back page, in colour)

The Victor No.522, 20th February 1971 (full page, in black-&-white)

The Hornet No.389, 20th February 1971 (full page, in black-&-white)

So not only was it short-lived, but also not very heavily publicised. It's interesting that one of the comics chosen for the promotion was "Sally" — but of course girls not only have brothers, but also are perfectly capable of enjoying Star Trek (even back in the barbarous wastelands of 1971).

The copy of "Sally" we have in the SPLAT Scan Archives is slightly creased, so for the ad shown above I've used a scan very kindly provided by Matt of


As you can see, the black-&-white version is identical to the colour.

We don't have any of these cereal packets in the Archives, but Peter Rice — sadly now deceased — of (who traded on eBay under the ID "heatedseats" — hence the labels) generously allowed us to use his scans of a pair of packet backs (with their fronts) which he was selling. The white squares are the envelopes containing the transfers. It seems that the right-hand packet is a larger size than the left-hand, since although the background panel artwork is identical, it reveals a few more stars & boulders.

He also flipped the panels over so that you can see what the inside of a cereal packet looks like! I know how much you all enjoy viewing this kind of thing…



Since first putting together this page, we've been given kind permission by retrotoyrevivals, who sells high-quality reproduction boxes on eBay, to display the photos which he sent me of one of his 7oz. (smaller) size boxes.

I expect you'd like to see what was actually in the packets, so here's a close-up of one of our envelopes, followed by three transfer sheets which have been extracted from their respective sachets.



Although in the SPLAT Scan Archives we only have the above three out of all six sheets, we've been sent photos of the others by various members over the years, so you can get an idea of the sheets comprising the rest of the range. Many thanks in particular to Ros Badcoe, who very kindly provided photos which we no longer need… since she then sold us the last immediately above!

Anyway, here are stop-gap images of the remaining, elusive, transfers:
