Birds.- Mayer (Henry Leonard) Illustrations of British Birds, 4 vol. in 3, first edition, 320 hand-coloured plates, including egg plates, tissue-guards, occasional marginal spotting, bookplate, near contemporary morocco, gilt, a little rubbed, slight bumping to corners and spine extremities, folio, [1835-41].

⁂ The publisher's name 'Longman & Co' does not feature a full-stop as is usual for the first issue of this work. Wood states that not only did Mayer execute and add additional plates for friends, but that "there were certainly two, possibly three issues of the first edition of the folio, and that the later ones were being published before the first was complete, the plates often being interchanged or duplicated." This means that there are rarely two copies alike.
