Algeria - French Département - Stamp Issue Date Needed - Year 1939

Please provide date of release of this Stamp.
Year 1939.

Most likely December 1

"A similar case concerns the Algerian postage stamp of 90c with the type "Rue De La Kasbah", printed in 1939, for single letters. But a tariff change of 1 December 1939, having increased the cost of these letters to 1F, rendered this 90c unusable for the function for which it was intended. But this time the copies of this stamp, initially very large print, were not destroyed, but overprinted 1F, by economy"

(from Wiki)

Scott does not give an issue date but notes that there are two overprint varieties. First was issued in 1939 and second was issued in 1940. Since the first is the last regular issue for 1939, that could be consistent with a Dec. 1 issue date.

Is this what your talking about ,

The OP's two copies appear to show the two overprint varieties (thick and thin) that boydxbiggs mentions and floortrader shows in his post. I.e., The OP scans are of two different stamps.

Maury lists an issue date of Dec 1, 1939 for both overprint varieties.
