Follow-up: Paulson passed in 2004, likely with a better memory than I have currently
I found the article below which has him at his Holiday, Florida address in December 1988 and again in January 1992, and some other correspondence that had him in St. Petersburg, Florida in 1971. Frank Robinson was not represented in the postcard set that I mentioned earlier, though Jackie Robinson was, and Earl Robinson was in there twice. There are at least two, possibly three other numbered series of postcards that have Paulson's stamp with either an Odessa, Dunedin, or Bradenton Florida address on the same standard Kodak backed RPPC stock, and he had a business under the name "Baseball Photo Service" that operated out of a Landis, North Carolina (1971 and 1980) and the St Petersburg, Florida address, as well as another business name of "Paulson Sports Advertising" out of the Landis address. I have also seen a Bristol, Tennessee address for him ca. 1983. All in addition to his original home base of Chicago, Illinois. Finally, the 1992 price list attached mentions him having a shot of Frank available.
Whew! So based on all of that, I would guesstimate him to be in Holiday, Florida from some time in the mid-1980's to at least 1992. Hope that helps!
