Greenland 1945 American Issue.  Pair of registered covers sent from Sukkertoppen Greenland to Vastervik Sweden 12-4-1948.  Both covers have "Lathework" pairs.
1 cover with a pair of 7 ore and 15 ore values,
1 cover with a pair of 10 ore and 2 kroner values.
Both are smaller size covers --- 5 1/2 x 4 inches (140 mm x 100 mm)

Both are philatelic in nature - cover with 2 kroner pair well overpaid, cover with 7 ore pair close to actual rate. But did get sent as both have a Vatervik receiver backstamp dated 4.5.48 - a month to get there.

Scott catalog is $40.00 per stamp as used.  8 x $40.00 = $320.00

Quite colorful.  From a National and International award-winning exhibit.
