A surprisingly late occurrence of the gold/blue Parlophone label. The ST tax code (in force April 10, 1946 - November 12, 1947) shows that this must be a 1946-1947 repress.
I've uploaded a detail from the cover where you discern the signature and added a clearer one of David Stone Martin for comparison, so your suspicion is also confirmed by the similarity.
Idle curiosity - might anyone know who the sleeve artist was? I can see what seems like a signature at the bottom, but can't make it out even with some digital jiggery-pokery. Is it David Stone Martin?
