Classic reference books

For MonoMonday with its theme 'Classic' , two of my own reference books, a Petite Larousse for its vintage encyclopaedia wisdom and one of the vintage Dutch architecture classics I have, opened on the pages about Gothic English architecture style, fan vaults in particular here. And one of DJ's owl bookends for still life value ;-) With thanks to Skeena for hosting this month and generally organising MonoMonday's hosting !
Tagging it also for the Still Life Sunday challenge by Nickimags888, like the Derelict Sunday challenge you can post entries the whole week, for this week until Saturday the tag is SLS9.

Thanks very much for your kind comments, stars and even two faves for yesterday's tulip !
