Have large lot of 200 of the Germany "Blue Flea",
unchecked for printing, plate errors or similar.

Hard to find in quantity, and ideal for study.

Would prefer to TRADE all, for other material I can use.
I collect:
first sets of Austria & Lombardy-Venetia [1850 series] - stamps and covers
German Colonies - stamps & covers
Canada - QV issues
Germany - DDR MNH to year 1951
