1D MULREADY/GRIMSBY UDC (LI468). A fine 1d Mulready envelope (Stereo A150) from Grimsby to Ross, Herefordshire cancelled fine red M.C. of Grimsby and alongside fine strike GRIMSBY udc in red (LI468), on reverse London receiver 1 JU 1840. Mulready presumably posted in Grimsby 31st May 1840 but unfortunately no date stamp. The udc unrecorded in county cat. in RED although Cowell records usage in 1845. (Ref 100697).
