Due to personal interests we have a long connection with a number of natural history organisations and the Hertfordshire Natural History Society was probably the first. Over time LTD has designed and produced a wide variety of items for them, including their website, leaflets, greetings cards, annual transactions, pop-up panels, etc. But probably the most interesting, and time consuming, are a series of hard-back county books on subjects including birds, flora, geology and landscape, butterflies and beetles. We are currently considering their overall identity.
