In 1934, a vase was unearthed in excavations at Tell ed-Duweir (Tell Lachish) in an expedition led by James Leslie Starkey. Theodor Gaster undertook to decipher the inscription on the vase, but before his decipherment was announced in The Times Newspaper the decipherment had been attributed to another. The items that comprise this collection are:

• Letter from Theodor Gaster to Colonel Hoysted, Secretary, Royal Asiatic Society, to lodge with him a 'lettre cachée' with his decipherment of the new script found on the vase. He claimed that he had originally communicated the decipherment to James Starkey but had suppressed its publication until the discovery of the ewer had been announced in The Times. However, in that time, another had been attributed with the decipherment. He was therefore sending a copy of his letter to Starkey, as proof of his claim, to both the Royal Asiatic Society and the Palestine Exploration Fund. With the letter is his copy of the decipherment and an envelope labelled 'Lettre cachée deposited with the R.A.S. by Theodor Gaster on 12.6.34'.
