Greenland. Accumulation ★★. BLOCKS OF FOUR (mainly) comprehensive stock 1960's-2000's in glassine envelopes with many complete sets, one section smaller glassine envelopes with often 1-2 blocks of each stamp, then one section somewhat larger glassine envelopes with NUMBERED MARGIN blocks of four 1-4 blocks of each stamp. Most stamps represented in both sections and hence a very high catalogue and face value!
