A good example of the early form -- straight-sides, flare- footed and flat-lidded. Lid and base marked with owners intials "IM' and with obscure wriggle work symbols. Rose and crown touch on handle. Fifty years ago my local pub had a beam thickly hung with the pewter mugs of the regulars -- each marked with owners's initials. Of course there was a "JF" hanging among them. Beer tastes great out of pewter.
