Here I starting a study of what others have done and what equipment there are to buy to solve this problem:

July 3, 2019 Travel, walks with old and new photos

• One old idea I have is to take old photos and then take new ones from the same place and compare. I have started with the island Riddarholmen in Stockholm. The old photography is from the 19th century. Much more complicated then I first thought, it will take long time, here is the beginning of the work:

25 april, 2019 Resor till sjöss

Min fars äventyr som sjöman under åren 1937 till 1945:

• Vem har inte drömt om att göra en jorden runt resa någon gång i sitt liv. Min pappa Evert gjorde det redan innan han var 20 år fyllda. Han mönstrade på handelsfartyg och hamnade ända borta i Kina och andra länder i Asien. Det här skedde delvis under Andra Världskriget, det var många fartyg som gick under från minor och torpeder, även svenska fartyg. Tre av fartygen han var på förliste pga detta, dock något efter att han mönstrat av. Trevligt nog har jag en hel del bilder till pappas alla berättelser om de här 7 åren till sjöss. Denna spännande historia kan ni följa här:

11 maj - 27 oktober, 2019 Utställning (OBS ! Sommaruppehåll !)

För er som gillar gamla båtar.
På Lidingö Museum kommer under sommaren 2019 pågå en utställning om Boghammar Marin. Mina minnen från min pappas berättelser är att han hade hört från den tidigare ägaren av hans Petterssonbåt Monalisa att den var byggd på Lidingö. Mina efterforskningar om Monalisa leder till varvet Gustafsson & Andersson på Lidingö som idag heter Boghammar:
