Patrick Tilley commissioned Busy Bees Nos. 3, 8 & 9 from an artist whose initials were probably "PB". Unfortunately, the relevant records to identify him have been lost, but his style is familiar & hopefully you or another visitor may recognise it, & then let us (or the artist himself) know. It won't be the first time we've been given a hot lead that way!
