The 1972 two disk "single" Santa Dog, supposedly about "a weiner dog in a Santa suit" and with a title that's an anagram of "Satan God", was the first published recording by The Residents.
The package was the founding release from Ralph Records and consisted of two 45s in a hand silk-screened gatefold sleeve which was printed to look like a Christmas card from an insurance company. This sleeve included '50s-ish drawings illustrating each song surrounded by text saying "Season's Greetings from Residents Uninc." and announcing the upcoming Vileness Fats project. 500 copies were pressed but only 400 were usable because of various problems. In addition, some of the sets were shrink-wrapped before the varnish on the silk-screening was dry and the packages had to be torn apart to be opened. Of the 400 usable copies, 300 were sent out to friends, record companies, and anyone else who came to mind. Richard Nixon was sent a copy, as was Frank Zappa, whose copy was returned "No Longer At Address" and was later given away in a contest.
In 2014 the original single was recreated by Superior Viaduct.
