you say 'marx wrote to lincoln', but the document in question was message of congralutions signed by 57 central council members on behalf of the international working men's association for which marx wrote the draft, and how does the this letter make it more credible that marx had previously written lincoln...
if i write to you, i say 'dear charles' or 'dear mr. brown', i sign off with 'cordially respectfully yours', michael or 'sincerely', michael hoover, and text of my letter includes me saying 'i this' and 'i that', in other words, *i* write to you...
above is very different from me writing draft of letter which is approved and signed on behalf of 'curmudgeon tendency' by carrol, yoshie, me, and whomever else may jump on board, and then sent to you, *i* have not written to you in this instance...
to best of my knowledge, we have no evidence that karl marx wrote to abraham lincoln in manner i've described - 'dear abe', 'yours truly, karl'...
