Safety plus System for your collection 
The ''steel cabinets" mentioned in the above newspaper reproduc- 
tion are installed in the Arnold Arboretum. They are none other than 
Art 
Steel Herbarium Cases 
These cases are used by the world's most famous collectors because 
they are scientifically constructed 
— to permit of fumigation without the necessity of transference 
— to keep out the much dreaded herbarium beetle 
— to guard your valuable herbs and shrubs from dust, dampness and fire 
— to enable you to easily file and find any particular specimen, at any time. 
If you value your collection you will appreciate the service these cases render. So 
why not learn something more about them. For your information and convenience we 
have prepared some special literature on the subject and we will be pleased to mail this to 
you if you will send in the coupon. Your request involves no obligation, of course.
