Kon Tiki mugs - did they come with little shooter mugs?

The Kon Tiki mug is a classic - in fact it's one of my faves. My question though is whether this mug came with associated 'shooter mugs' that sat on the top of the mug. I'd never heard of or seen these before, but as this picture show, there appeared to be a production of these mugs with 4 little individual shot mugs. I understand they came as a pack of four Kon Tiki mugs with 4 shooter mugs that were palced on top. Can anyone shed any light on this?

Naaaaw, I don't think so. They don't match in glaze and style, and the Kon Tikis were Otagiri restaurant industry mugs, nobody served cocktails that way back then.
The four dark lil' mugs were used as a stack, independent from the Kon Tikis, yes, but not together.

Yeah, I thought that was probably the case. Looks like someone added 2 & 2 together and got 5.
