THIS evening's duologue is the result of an adventurous visit paid to Petra, famous as ' the rose-red city half as old as time,' by Mr. Bomberg and his wife in 1924.

They stayed there for six months, living under canvas, and with an armed escort sent for their protection by the Government of Trans-Jordania. They were visited there by Mrs. Stewart Erskine , the well-known authoress and traveller, who will exchange reminiscences this evening with Mr. Bomberg. The letter's exhibition of pictures at the Leicester Galleries on his return from Petra aroused great interest in artistic circles. He is now holding a private exhibition in his studio at [address removed], and any reader who wishes to obtain an invitation should write to him there.
