I like "sleeping giant" papers. Imagine writing a paper that after 26 years amassed 17 citations (4 of them self citations). Yes, this was some decades ago the citation rate was generally lower then, but still, the expected number of total citations of the paper has got to be low...

The paper sits at 5213 citations, growing at a rate of 200-300/yr. The paper is Minkowski's mu->e gamma paper, which is really about neutrinos It's also interesting that even after SK got 5σ for oscillations in '98, people didn't remember this paper for a few years inspirehep.net/literature/4...
