A picture would sure help. Without one, my guess is that the cigars were from the FABRICA de TABACOS factory, one of the oldest cigar factories in Havana. "Marcos Morales y Ca." is the distributor or import company of that box. "Regalia de Londres" is a Romeo y Julieta cigar, and "Flor Fina" was probably the size. I believe this to be in the Civil War circa from some old books I found online. Again, without a picture, these are guesstimates only.
