Pink lustre plaques from c1830s from as yet unidentified potteries.  The top row have a decorative element that Ian Holmes has described as 'colliding meteorites' or two fallen palm trees. This appears on hand-painted plaques with the Dixon impress.  However, the rectangular plaque is very similar to a form used by Maling.  The transferred block text with shadows on the second row of plaques, appears on 'Seek Ye The Lord' plaques attributed to Maling.

The verse 'But One Thing is Needful' (Luke X, 42) inspired the sermon, 'The One Thing Needful', by the preacher C H Spurgeon, 15 October 1871. 

'Search the Scriptures' is a title of a sermon by the Reverend C H Spurgeon delivered January 17, 1858.  As the title is not a biblical quotation, the plaque could have been produced around that date, perhaps to be sold on tour?  However, it looks to be of an early form (c1830s-40s).  So it is possible that Spurgeon appropriated the title from an earlier source.

I haven't yet been able to match the very distinctive hand-painted lettering and decoration with plaques from any other pottery.  The text 'Rejoice in thy Saviour' appears to be unique to these plaques.

Put thy trust in the Lord
And thou shalt be saved
THOU GOD SEEST ME
I know all the fowls upon the
Mountains: & the Beasts of the
Field are in my sight. P50

The black and yellow decoration of the left plaque, and the style of the mould, very similar to those used by Maling. Read more here. The pink-lustred central transfer also appears to be a Maling feature.

Moore & Co used a similar transfer, though with the image in reverse, on a bowl (read more here).
